conflict of interest
As the data suggesting that homeopathy is effective for improving health is – to put it mildly – less than convincing, a frantic search is currently on amongst homeopaths and their followers to identify a specific condition for which the evidence is stronger than for all conditions pooled into one big analysis. If they could show that it works for just one disease, they could celebrate this finding and henceforth use it for refuting doubters stating that highly diluted homeopathic remedies are pure placebos. One such condition is allergic rhinitis; there have been several trials suggesting that homeopathy might be effective for it, and therefore it is only logical that homeopathy-promoters want to summarise these data in order to silence sceptics once and for all.
A new paper ought to be seen in this vein. It is systematic review by the Mathie group with the stated aim “to evaluate the efficacy and effectiveness of homeopathic intervention in the treatment of seasonal or perennial allergic rhinitis (AR).”
Randomized controlled trials evaluating all forms of homeopathic treatment for AR were included in a systematic review (SR) of studies published up to and including December 2015. Two authors independently screened potential studies, extracted data, and assessed risk of bias. Primary outcomes included symptom improvement and total quality-of-life score. Treatment effect size was quantified as mean difference (continuous data), or by risk ratio (RR) and odds ratio (dichotomous data), with 95% confidence intervals (CI). Meta-analysis was performed after assessing heterogeneity and risk of bias.
Eleven studies were eligible for SR. All trials were placebo-controlled except one. Six trials used the treatment approach known as isopathy, but they were unsuitable for meta-analysis due to problems of heterogeneity and data extraction. The overall standard of methods and reporting was poor: 8/11 trials were assessed as “high risk of bias”; only one trial, on isopathy for seasonal AR, possessed reliable evidence. Three trials of variable quality (all using Galphimia glauca for seasonal AR) were included in the meta-analysis: nasal symptom relief at 2 and 4 weeks (RR = 1.48 [95% CI 1.24-1.77] and 1.27 [95% CI 1.10-1.46], respectively) favoured homeopathy compared with placebo; ocular symptom relief at 2 and 4 weeks also favoured homeopathy (RR = 1.55 [95% CI 1.33-1.80] and 1.37 [95% CI 1.21-1.56], respectively). The single trial with reliable evidence had a small positive treatment effect without statistical significance. A homeopathic and a conventional nasal spray produced equivalent improvements in nasal and ocular symptoms.
The authors concluded that the low or uncertain overall quality of the evidence warrants caution in drawing firm conclusions about intervention effects. Use of either Galphimia glauca or a homeopathic nasal spray may have small beneficial effects on the nasal and ocular symptoms of AR. The efficacy of isopathic treatment of AR is unclear.
Extracts of Galphimia glauca (GG) have been used traditionally in South America for the treatment of allergic conditions, with some reports suggesting effectiveness. A 1997 meta-analysis of 11 clinical trials (most of them of very poor quality) of homeopathic GG suggested this therapy to be effective in the treatment of AR. In 2011, I published a review (FACT 2011, 16 200-203) focussed exclusively on the remarkable set of RCTs of homeopathic Galphimia glauca (GG). My conclusions were as follows: three of the four currently available placebo-controlled RCTs of homeopathic GG suggest this therapy is an effective symptomatic treatment for hay fever. There are, however, important caveats. Most essentially, independent replication would be required before GG can be considered for the routine treatment of hay fever. Since then, no new studies have emerged.
I am citing this for two main reasons:
- There is nothing homeopathic about the principle of using GG for allergic conditions; according to homeopathic theory GG extracts would need to cause allergies for GG to have potential as a homeopathic allergy remedy. Arguably, the GG trials should therefore have been excluded from this meta-analysis for not following the homeopathic principal of ‘like cures like’.
- All the RCTs of GG were done by the same German research group. There is not a single independent replication of their findings!
Seen from this perspective, the conclusion by Mathie et al, that the use of either Galphimia glauca … may have small beneficial effects on the nasal and ocular symptoms of AR, seems more than a little over-optimistic.
We have discussed this notorious problem before: numerous charities (such as one that treats HIV and malaria with homeopathy in Botswana, or the one claiming that homeopathy can reverse cancer) are a clear danger to public health. I have previously chosen the example of ‘YES TO LIFE’ and explained that they promote unproven and disproven alternative therapies as cures for cancer (and if you want to get really sickened, look who act as their supporters and advisors). It is clear to me that such behaviour can hasten the death of many vulnerable patients.
Yet, many such charities get tax and reputational benefits by being registered charities in the UK. The question is CAN THIS SITUATION BE JUSTIFIED?
Currently, the UK Charity commission want to answer it. Specifically, they are asking you the following question:
- Question 1: What level and nature of evidence should the Commission require to establish the beneficial impact of CAM therapies?
- Question 2: Can the benefit of the use or promotion of CAM therapies be established by general acceptance or recognition, without the need for further evidence of beneficial impact? If so, what level of recognition, and by whom, should the Commission consider as evidence?
- Question 3: How should the Commission consider conflicting or inconsistent evidence of beneficial impact regarding CAM therapies?
- Question 4: How, if at all, should the Commission’s approach be different in respect of CAM organisations which only use or promote therapies which are complementary, rather than alternative, to conventional treatments?
- Question 5: Is it appropriate to require a lesser degree of evidence of beneficial impact for CAM therapies which are claimed to relieve symptoms rather than to cure or diagnose conditions?
- Question 6: Do you have any other comments about the Commission’s approach to registering CAM organisations as charities?
I am sure that most readers of this blog have something to say about these questions. So, please carefully study the full document, go on the commission’s website, and email your response to: firstname.lastname@example.org . Don’t delay it; do it now!
On this blog, we have had (mostly unproductive) discussions with homeopath so often that sometimes they sound like a broken disk. I don’t want to add to this kerfuffle; what I hope to do today is to summarise a certain line of argument which, from the homeopaths’ point of view, seems entirely logical. I do this in the form of a fictitious conversation between a scientist (S) and a classical homeopath (H). My aim is to make the reader understand homeopaths better so that, future debates might be better informed.
HERE WE GO:
S: I have studied the evidence from studies of homeopathy in some detail, and I have to tell you, it fails to show that homeopathy works.
H: This is not true! We have plenty of evidence to prove that patients get better after seeing a homeopath.
S: Yes, but this is not because of the remedy; it is due to non-specific effect like the empathetic consultation with a homeopath. If one controls for these factors in adequately designed trials, the result usually is negative.
I will re-phrase my claim: the evidence fails to show that highly diluted homeopathic remedies are more effective than placebos.
H: I disagree, there are positive studies as well.
S: Let’s not cherry pick. We must always consider the totality of the reliable evidence. We now have a meta-analysis published by homeopaths that demonstrates the ineffectiveness of homeopathy quite clearly.
H: This is because homeopathy was not used correctly in the primary trials. Homeopathy must be individualised for each unique patient; no two cases are alike! Remember: homeopathy is based on the principle that like cures like!!!
S: Are you saying that all other forms of using homeopathy are wrong?
H: They are certainly not adhering to what Hahnemann told us to do; therefore you cannot take their ineffectiveness as proof that homeopathy does not work.
S: This means that much, if not most of homeopathy as it is used today is to be condemned as fake.
H: I would not go that far, but it is definitely not the real thing; it does not obey the law of similars.
S: Let’s leave this to one side for the moment. If you insist on individualised homeopathy, I must tell you that this approach can also be tested in clinical trials.
H: I know; and there is a meta-analysis which proves that it is effective.
S: Not quite; it concluded that medicines prescribed in individualised homeopathy may have small, specific treatment effects. Findings are consistent with sub-group data available in a previous ‘global’ systematic review. The low or unclear overall quality of the evidence prompts caution in interpreting the findings. New high-quality RCT research is necessary to enable more decisive interpretation.
If you call this a proof of efficacy, I would have to disagree with you. The effect was tiny and at least two of the best studies relevant to the subject were left out. If anything, this paper is yet another proof that homeopathy is useless!
H: You simply don’t understand homeopathy enough to say that. I tried to tell you that the remedy must be carefully chosen to fit each unique patient. This is a very difficult task, and sometimes it is not successful – mainly because the homeopaths employed in clinical trials are not skilled enough to find it. This means that, in these studies, we will always have a certain failure rate which, in turn, is responsible for the small average effect size.
S: But these studies are always conducted by experienced homeopaths, and only the very best, most experienced homeopaths were chosen to cooperate in them. Your argument that the trials are negative because of the ineffectiveness of the homeopaths – rather than the ineffectiveness of homeopathy – is therefore nonsense.
H: This is what you say because you don’t understand homeopathy!
S: No, it is what you say because you don’t understand science. How else would you prove that your hypothesis is correct?
H: Simple! Just look at individual cases from the primary studies within this meta-analysis . You will see that there are always patients who did improve. These cases are the proof we need. The method of the RCT is only good for defining average effects; this is not what we should be looking at, and it is certainly not what homeopaths are interested in.
S: Are you saying that the method of the RCT is wrong?
H: It is not always wrong. Some RCTs of homeopathy are positive and do very clearly prove that homeopathy works. These are obviously the studies where homeopathy has been applied correctly. We have to make a meta-analysis of such trials, and you will see that the result turns out to be positive.
S: So, you claim that all the positive studies have used the correct method, while all the negative ones have used homeopathy incorrectly.
H: If you insist to put it like that, yes.
S: I see, you define a trial to have used homeopathy correctly by its result. Essentially you accept science only if it generates the outcome you like.
H: Yes, that sounds odd to you – because you don’t understand enough of homeopathy.
S: No, what you seem to insist on is nothing short of double standards. Or would you accept a drug company claiming: some patients did feel better after taking our new drug, and this is proof that it works?
H: You see, not understanding homeopathy leads to serious errors.
S: I give up.
The aim of this paper was to systematically review surveys of 12-month prevalence of homeopathy use by the general population worldwide. Studies were identified via database searches to October 2015. Study quality was assessed using a six-item tool. All estimates were in the context of a survey which also reported prevalence of any complementary and alternative medicine use. A total of 36 surveys were included. Of these, 67% met four of six quality criteria.
Twelve-month prevalence of treatment by a homeopath was reported in 24 surveys of adults (median 1.5%, range 0.2–8.2%). Estimates for children were similar to those for adults. Rates in the USA, UK, Australia and Canada all ranged from 0.2% to 2.9% and remained stable over the years surveyed (1986–2012). Twelve-month prevalence of all use of homeopathy (purchase of over-the-counter homeopathic medicines and treatment by a homeopath) was reported in 10 surveys of adults (median 3.9%, range 0.7–9.8%) while a further 11 surveys which did not define the type of homeopathy use reported similar data. Rates in the USA and Australia ranged from 1.7% to 4.4% and remained stable over the years surveyed. The highest use was reported by a survey in Switzerland where homeopathy is covered by mandatory health insurance.
The authors concluded that each year a small but significant percentage of these general populations use homeopathy. This includes visits to homeopaths as well as purchase of over-the-counter homeopathic medicines.
These data thus indicate that the percentage of the adult general population using homeopathy over the previous 12 months was in the range of 0.7–9.8%, with a median estimate of 3.9%, and the percentage accessing treatment by a homeopath over the previous 12 months was in the range of 0.2–8.2%, with a median estimate of 1.5%. The data also suggest that, over the last few decades, use of homeopathy has remained fairly stable. These facts are in sharp contrast to the claims by homeopaths that:
- Homeopathy is hugely popular.
- Homeopathy is being used by more and more people across the globe.
- Homeopathy is the medicine of the future.
The well-documented and undeniable unpopularity of homeopathy begs the question, I think, why so many people seem to get so excited about homeopathy. The level of usage is nothing to write home about! Therefore, why don’t we just put it down to an aberration like believing the earth is flat? Why don’t we just concede that some minor, harmless stupidity will always exist in some people’s minds?
Here are some reasons why:
- It is not about the amount of people using homeopathy, but about the principle that any of the increasingly scarce public funds for healthcare are wasted on something as irrational and useless as homeopathy.
- Homeopathy makes a mockery of EBM.
- Homeopathy and homeopaths are by no means harmless.
- Homeopaths tell too many lies to be allowed to get away with them.
- Homeopathy and its followers systematically undermine rational thought.
The aim of this pragmatic study was “to investigate the effectiveness of acupuncture in addition to routine care in patients with allergic asthma compared to treatment with routine care alone.”
Patients with allergic asthma were included in a controlled trial and randomized to receive up to 15 acupuncture sessions over 3 months plus routine care, or to a control group receiving routine care alone. Patients who did not consent to randomization received acupuncture treatment for the first 3 months and were followed as a cohort. All trial patients were allowed to receive routine care in addition to study treatment. The primary endpoint was the asthma quality of life questionnaire (AQLQ, range: 1–7) at 3 months. Secondary endpoints included general health related to quality of life (Short-Form-36, SF-36, range 0–100). Outcome parameters were assessed at baseline and at 3 and 6 months.
A total of 1,445 patients were randomized and included in the analysis (184 patients randomized to acupuncture plus routine care and 173 to routine care alone, and 1,088 in the nonrandomized acupuncture plus routine care group). In the randomized part, acupuncture was associated with an improvement in the AQLQ score compared to the control group (difference acupuncture vs. control group 0.7 [95% confidence interval (CI) 0.5–1.0]) as well as in the physical component scale and the mental component scale of the SF-36 (physical: 2.5 [1.0–4.0]; mental 4.0 [2.1–6.0]) after 3 months. Treatment success was maintained throughout 6 months. Patients not consenting to randomization showed similar improvements as the randomized acupuncture group.
The authors concluded that in patients with allergic asthma, additional acupuncture treatment to routine care was associated with increased disease-specific and health-related quality of life compared to treatment with routine care alone.
We have been over this so many times (see for instance here, here and here) that I am almost a little embarrassed to explain it again: it is fairly easy to design an RCT such that it can only produce a positive result. The currently most popular way to achieve this aim in alternative medicine research is to do a ‘A+B versus B’ study, where A = the experimental treatment, and B = routine care. As A always amounts to more than nothing – in the above trial acupuncture would have placebo effects and the extra attention would also amount to something – A+B must always be more than B alone. The easiest way of thinking of this is to imagine that A and B are both finite amounts of money; everyone can understand that A+B must always be more than B!
Why then do acupuncture researchers not get the point? Are they that stupid? I happen to know some of the authors of the above paper personally, and I can assure you, they are not stupid!
I am afraid there is only one reason I can think of: they know perfectly well that such an RCT can only produce a positive finding, and precisely that is their reason for conducting such a study. In other words, they are not using science to test a hypothesis, they deliberately abuse it to promote their pet therapy or hypothesis.
As I stated above, it is fairly easy to design an RCT such that it can only produce a positive result. Yet, it is arguably also unethical, perhaps even fraudulent, to do this. In my view, such RCTs amount to pseudoscience and scientific misconduct.
CBC news (Canada) reported yesterday that, more than a decade ago, the Manitoba Chiropractic Health Care Commission had been tasked to review the cost effectiveness of chiropractic services. It therefore prepared a report in 2004 for the Manitoba province and the Manitoba Chiropractors Association. Since then, this report has been kept secret. The report makes 37 recommendations, including:
- Manitoba Health should limit its funding to “chiropractic treatment of acute lower back pain.”
- Manitoba Health should provide “limited coverage of the treatment of neck pain.” The report called the literature around the efficacy of chiropractic care for neck pain “ambiguous or at best weakly supportive” and noted such treatment carried a “not insignificant safety risk.”
- Manitoba Health should not fund chiropractic treatment anyone under 18 “as the literature does not unequivocally justify” the “efficacy or safety” of such treatment.
A Manitoba Ombudsman’s Office report from 2012 might shed some light on why the Manitoba Chiropractic Health Care Commission’s report was never made public. Someone had attempted to get a copy of the report, but large parts of it were redacted. “Access to this record was refused on the basis that disclosure would be harmful to a third party’s business interest,” the ombudsman report notes, “and harm the economic or financial interests or negotiating position of a public body.”
The report also challenged claims that chiropractic treatments can be address a wide variety of medical conditions. It stated that there was not enough evidence to conclude chiropractic treatments are effective in treating muscle tension, migraines, HIV, carpal tunnel syndrome, gastrointestinal problems, infertility or cancer, or as a preventive care treatment. It also said there was not enough evidence to conclude chiropractic treatments are effective for children.
The report urged Manitoba Health to establish a monitoring system to keep a closer eye on “the advertising practices of the Manitoba Chiropractors Association and its members to ensure claims regarding treatments are restricted to those for which proof of efficacy and safety exist.” It suggested the government should have regulatory powers over chiropractic ads.
A recent CBC I-Team investigation found Manitoba chiropractors advertising treatment for a wide range of conditions including Alzheimer’s, autism and pediatric services. The commission report contained sharp criticisms of previous reports that suggested funding chiropractic care could save the health-care system money. Dr. Pranlal Manga authored two widely cited reports which claim that by offering publicly funded chiropractic care, provinces can cut health-care costs. “The Manga study on Manitoba must be rejected as a guide to public policy,” the commission report states, “because its assumptions, methodology and costing of recommendations are all deeply flawed.” The reports states, “What limited evidence the Commission has suggests he [Manga] grossly exaggerates possible medical savings.” Dr. Manga did not respond to CBC’s repeated attempts to contact him.
The commission report also made recommendations around the use of X-ray machines by chiropractors. It suggested chiropractors not own and operate X-ray machines “Given the restrictive conditions under which X-rays are advisable, their poor correlation with low-back problems, their apparent limitation as a guide to appropriate treatment …[and] the apparent complete lack of monitoring [of] the use of X-ray by chiropractors.” Instead, it recommended consulting with radiologists when imaging is deemed necessary. “The Commission is of the view that the public interest, and even chiropractic itself, would be better served if chiropractors had access to radiologists for this service, rather than perform it themselves,” the report said.
All three report authors declined comment. Calls to Dave Chomiak, who was health minister at the time the report was prepared, were not returned. In an email to CBC, Manitoba Chiropractors Association president Perry Taylor said, “I personally have never seen this 13-year-old document and [it] pre-dates my time as President. As such I have no comment on this.” The CBC I-Team offered to go through the report with Taylor but he did not respond.
This report seems to confirm much of what we have discussed repeatedly on this blog: Chiropractic is not nearly as effective and safe as chiropractors try to make us believe. To hide this fact is certainly dishonest and unethical, but it is in some ways understandable: this knowledge would directly threaten the income of most chiropractors.
Yesterday I commented on another post: “the conflict of interest seems obvious: if homeopaths speak the truth, they are out of business. therefore, they are taught untruths from the first day of their training and eventually end up believing them. there is only one solution, as far as I can see: regulators must prevent them from making false claims. if not, this will go on for another 200 years and damage many patients’ health”. In the light of the above report, I will now re-phrase this: the conflict of interest seems obvious: if chiropractors allowed the truth to be known, they would soon be out of business. Therefore, they are taught untruths from the first day of their training and many end up believing them. There is only one solution, as far as I can see: regulators must prevent chiropractors from making false claims. If not, this abuse will go on for another 120 years and damage many patients’ health.
Charlotte Leboeuf-Yde, DC,MPH,PhD, is professor in Clinical Biomechanics at the University of Southern Denmark and works at the French-European Institute of Chiropractic in Paris. She is a chiropractor with extensive research experience, for example, she was one of the first chiropractors to have studied adverse reactions of spinal manipulation.
Charlotte certainly knows a thing or two about adverse effects of spinal manipulation, and I have always found her work interesting. Therefore, I was delighted to find a recent blog post where she discussed the Cassidy study of 2008 and two opposed views on the validity of this much-discussed paper.
One team (Paulus &Thaler) argued, Charlotte explained, that the Cassidy case-control study is faulty, because vertebro-basilar stroke in general was not separated from stroke specifically caused by vertebral artery dissections, the presumed culprit in cervical spinal manipulation. According to Paulus & Thaler, this would potentially result in a dilution of ‘real’ manipulative-related strokes among all other causes of stroke that are much more common. They argue that the Cassidy-analyses therefore were polluted by this misclassification, whereas the other team (Murphy et al) vehemently disagrees.
The final word is clearly not yet pronounced on this issue, Charlotte concluded, and both teams agree that research has to address various methodological challenges to obtain a trustable answer. Nevertheless, without an international collaboration involving prospective cases this seems an almost impossible task, particularly in view of the rarity of the condition; problems in capturing all cases (going from the reversible to the permanent injuries); the likely large anatomical and physiological variations between individuals; and the daunting task of obtaining relevant and precise descriptions of treatments from a multitude of practitioners.
In the meantime, Charlotte concluded, “practitioners and patients have to make a decision, similarly to judging risk in other walks of life, such as, should I take the plane or stay at home?”
I have always thought highly of Charlotte’s work, however, her conclusion made me doubt whether my high opinion of her reasoning was justified.
Should I take the plane or stay at home?
This question is not remotely similar to the question “should I have chiropractic upper neck manipulation or not?”
Here are a the two main reasons why:
- Taking the plane of demonstrably effective in transporting you from A to B, while neck manipulation is not demonstrably effective for anything.
- If you want to go from A to B [assuming B is far way], you need to fly. If you have neck pain or other symptoms, you can employ plenty of therapies other than neck manipulations.
Charlotte Leboeuf-Yde, DC,MPH,PhD, may be a professor in Clinical Biomechanics etc., etc., however, logical and critical thinking do not seem to be her forte.
So, how should we deal with the risks of chiropractic neck manipulations? I think, we should deal with them as responsible healthcare professionals deal with any other suspected therapeutic risks: we must ask whether the known risks of the treatment outweigh the known benefits (as they do with spinal manipulation). If that is so, we have an ethical, legal and moral duty not to employ the therapy in question in routine care. At the same time, we must focus or research efforts on producing full clarity about the open questions. It’s called the precautionary principle!
The ‘SOCIETY OF HOMEOPATHS’ (SoH) have published an official complaint they recently filed with the BBC. As it gives an intriguing insight into their mind-set, I could not resist reproducing it here (warts and all):
“Prompted by the interview with Simon Stevens of NHS England on the Today Programme, on 31st March, the Society of Homeopaths deplores the lack of balance in the BBC’s coverage of Homeopathy and urges you to review your approach to coverage of the subject.
During the Today interview, following wide-ranging discussion of issues around the future of the NHS, Sarah Montague suddenly threw in a question about the amount spent on Homeopathy within the NHS, evidently catching Mr Stevens unawares.
The annual budget of the NHS is approximately £110billion. Of this, £4million per year (0.0036 of the NHS budget) is spent on Homeopathy. This hardly justifies the unbalanced and hectoring approach from Sarah Montague.
We acknowledge that it is not always possible or necessary to achieve balance on a particular topic within a single programme but the BBC seems to have a consistent line across all of its platforms of opposition to, and disparagement of, Homeopathy. A recent example is a piece on the Health section of the BBC website in October 2106 by Nick Tiggle which displayed no balance at all and denigrated Homeopathy and Homeopaths with little or no space given to alternative views.
From these and other instances, it seems clear that the BBC has a biased attitude towards Homeopathy, which may be the result of relying too heavily on a small number of ‘experts’, who openly and persistently campaign against complementary and alternative medicine. These ‘experts’ operate in a similar way to climate change deniers, referring to a limited range of research, often of poor quality, to support their claims that there is ‘no evidence for homeopathy’.
We look forward to BBC programmes which fulfill its mission to explain and provide balance and coverage of the positive effects of Homeopathy.
Mark Taylor Chief Executive Society of Homeopaths”

This hardly needs a comment – perhaps just 6 short points:
- To the best of my knowledge, the BBC has a policy of not being seen to be biased. The discussion referred to above was about the NHS stopping to pay for treatments that are either not effective (e. g. cough syrups) or cheaper to buy OTC than on prescription (e. g. paracetamol). Homeopathy is both. Therefore it would have even been biased NOT to bring homeopathy into the discussion.
- To claim the BBC-interviewer caught Stevens off guard is just silly: when you go on the radio to discuss such issues, homeopathy MUST be on your mind.
- To claim that the BBC is generally biased against homeopathy (on the basis of two anecdotes) is equally silly. The SoH should have done some systematic research on this – perhaps they did and found it failed to support their point? – this would have shown that there is plenty of (far too much) pro-homeopathy stuff on the BBC.
- To say or imply that homeopathy is of debatable or even no value to the NHS does not disclose bias; on the contrary, it is a reflection of the scientific truth which the BBC has an obligation to report.
- With their complaint, the SoH disclose an embarrassing degree of naivety and an alarming detachment from reality.
- Whichever way a rational observer might look at this, the BBC should in future become a much more outspoken defender of the scientific truth – on homeopathy and everything else!!!
D D Palmer was born on March 7, 1845; so, why do chiros celebrate the ‘CHIROPRACTIC AWARENESS WEEK’ from 10 – 16 of April? Perhaps out of sympathy with the homeopaths (many US chiros also use homeopathy) who had their ‘big week’ during the same period? Please tell me, I want to know!
Anyway, the HAW almost ‘drowned’ the CAW – but only almost.
The British Chiropractic Association did its best to make sure we don’t forget the CAW. On their website, we find an article that alerts us to their newest bit of research. Here are some excerpts:
The consumer survey by the British Chiropractic Association (BCA) of more than 2,000 UK adults who currently suffer from back or neck pain, or have done so in the past, found that almost three in five (56%) people experienced pain after using some form of technological device. Despite this, only 27% of people surveyed had limited or stopped using their devices due to concerns for their back or neck health and posture. The research showed people were most likely to experience back or neck pain after using the following technological devices:
• Laptop computer (35%)
• Desktop computer (35%)
• Smart phone (22%)
• Tablet (20%)
• Games console (17%)
The age group most likely to experience back or neck pain when using their smart phone were 16-24 year olds, while nearly half (45%) of young adults 25-34 year olds) admitted to experiencing back or neck pain after using a laptop. One in seven (14%) 16-24 year olds attributed their back or neck pain to virtual reality headsets.
As part of Chiropractic Awareness Week (10-16 April) the BCA is calling for technology companies to design devices with posture in mind, to help tech proof our back health. BCA chiropractor Rishi Loatey comments: “We all know how easy it is to remain glued to our smart phone or tablet, messaging friends or scrolling through social media. However, this addiction to technology could be causing changes to posture, which can lead to increased pressure on the muscles, joints and discs in the spine. Technology companies are now starting to issue older phone models which hark back to a time before smart phones enabled people to do everything from check emails and take pictures, to internet banking. Returning to a time of basic functionality, which may see people look to limit the time spent on their phone, can only be good news for our backs. Yet, in an age where people can now track their health and wellbeing using their phone, technology companies should also start looking at ways to make their devices posture friendly from the outset, encouraging us to take time away from our desks and breaks from our scrolling, gaming and messaging.”

So, here we have it: another piece of compelling, cutting edge research by the BCA. They have made us giggle before but rarely have I laughed so heartily about a ‘professional’ organisation confusing so unprofessionally correlation with causation.
Considering the amount of highly public blunders they managed to inflict on the profession in recent years, I have come to the conclusion that the BCA is a cover organisation of BIG PHARMA with the aim of giving chiropractic a bad name!
‘What Doctors Don’t Tell You’ (WDDTY) have been shown to be strangely economical with the truth many times before (for instance here, here and here). Now they have published an article entitled ‘Ombudsman investigates ‘flawed’ homeopathic study that claimed it doesn’t work’ It attacks in no uncertain terms the ‘NHMRC Statement on Homeopathy and NHMRC Information Paper – Evidence on the effectiveness of homeopathy for treating health conditions’ which I believe to be a sound evaluation of homeopathy and therefore have mentioned repeatedly on this blog. Here is what WDDTY stated:
START OF QUOTE
A major and influential review of homeopathy concluded that the controversial therapy doesn’t work—but it was so riddled with error and bad science that it’s sparked an official ombudsman investigation.
The world’s media announced that homeopathy was a scam after the Australia government’s National Health and Medical Research Council (NHMRC) published its findings in 2015 that “there are no health conditions for which there is reliable evidence that homeopathy is effective.”
But now the Commonwealth Ombudsman is investigating the review’s procedures after receiving reports of inaccuracies, mishandling of evidence and conflicts of interest.
The review has been triggered by the Australian Homeopathic Association (AHA), supported by the Homeopathic Research Institute (HRI), which began questioning the review’s processes after several solid studies that demonstrated homeopathy’s benefits had been overlooked.
The NHMRC review team set arbitrary parameters that only studies that involved more than 150 people—and which met standards that even drug trials rarely achieve—would be considered. Those requirements reduced the number of qualifying studies to just five—from an initial pool of more than 1,800 trials—and none of these showed that homeopathy was effective.
One of the NHMRC’s own reviewers produced a mysterious first report that has never been published, and hasn’t been released despite Freedom of Information requests.
And the AHA has discovered that Prof Peter Brooks, chair of the NHMRC committee that carried out the homeopathy review, never declared that he was a member of the anti-homeopathy lobby group, Friends of Science in Medicine.
There are solid studies that demonstrate homeopathy is effective against childhood diarrhea, sinusitis and hay fever—but they all involve fewer than 150 people, said HRI chief executive Rachel Roberts. “The public has a right to know that there are high quality studies showing homeopathy works for some medical conditions—information that was lost only due to NHMRC’s mishandling of the evidence.”
The homeopaths aren’t alone in challenging the NHMRC review: Australia’s independent Cochrane Centre said its conclusions are not an accurate reflection of the evidence, and a second expert also said he felt “uncertain of the definitive nature of the report’s conclusions.”

As it happens, I am in contact with the lead author of this report, Paul Glasziou, not least because he very kindly wrote the foreword for my book HOMEOPATHY, THE UNDILUTED FACTS. So, we corresponded and discussed the latest WDDTY diatribe. Thus I am now in a position to put a few things straight (I hope Paul does not mind).
ISSUE 1. – The NHMRC review team set arbitrary parameters that only studies involving more than 150 people—and which met standards that even drug trials rarely achieve—would be considered.
The truth is that report focused on systematic reviews of trials, not individual trials. The 57 included systematic reviews found 176 individual trials which covered 61 conditions: an average of about 3 trials per condition. But some conditions only had 1 trial, and one small trial would, of course, not be considered a reasonable basis for reliable conclusions. GRADE – the international standard for assessing evidence – downgrades reviews for “imprecision” – the GRADE Handbook suggests “whenever there are sample sizes that are less than 400, review authors and guideline developers should certainly consider rating down for imprecision.” Hence the criterion of 150 which the Australians decided to use is considerably more lenient than the current GRADE guideline.
ISSUE 2 – Those requirements reduced the number of qualifying studies to just five—from an initial pool of more than 1,800 trials—and none of these showed that homeopathy was effective.
This is simply not correct. The report found 57 systematic reviews that contained 176 individual trials, not 5. These 176 trials, which covered 61 conditions, formed the body of evidence for the NHMRC report’s conclusions.
ISSUE 3 – There are solid studies that demonstrate homeopathy is effective against childhood diarrhoea, sinusitis and hay fever—but they all involve fewer than 150 people, said HRI chief executive Rachel Roberts.
The NHMRC report focused on systematic reviews that covered all trials for individual conditions. Given the conventional p-value of 0.05, one would expect 1 in 20 single trials to be “false positives”. So with 176 trials, we expect about 9 “false positive” trials. But using systematic reviews that combine all trials for individual conditions, reduces this risk of false positives. Most national evidence review bodies require more than 1 trial, e.g, the FDA requires 2 positive trials, whereas many others require a systematic review which has at least 2 trials. Replication of findings is obviously a cornerstone of science.
ISSUE 4 The homeopaths aren’t alone in challenging the NHMRC review: Australia’s independent Cochrane Centre said its conclusions are not an accurate reflection of the evidence, and a second expert also said he felt “uncertain of the definitive nature of the report’s conclusions.”
The truth is that the Cochrane Centre, which provided an independent check during the processes of the NHMRC review, concluded that “Overall, the conclusions arising from the review appear justified based on the evidence presented.”
I REST MY CASE.
