It is time, I think, to call an end to this series of articles on ‘drowning in a sea of misinformation’. Not that I have covered every contributor to and aspect of it. On the contrary, I could have carried on for another couple of weeks writing a post every day as I did during the last 15 days. But it was getting a bit boring – at least for me. So, for the last post, I have decided to briefly discuss politicians. In my view, they are crucially important in this context, as they create the general atmosphere and framework in which all the other mis-informers can thrive.

Peter Hain (Labour) is a campaigner for homeopathy and wants to see it widely used on the NHS. He was quoted as saying: “I first came to know about homeopathy through my son who as a baby suffered from eczema. He had it a couple of years but with conventional treatment the eczema was getting progressively worse and at the age of four he also developed asthma. We turned to homeopathy out of desperation and were stunned with the positive results. Since then I have used homeopathy for a wide variety of illnesses, but I rely on arnica as it’s excellent for treating the everyday bruises and shocks to the system we face. My view is that homeopathy and conventional medicines must remain side by side under the NHS to offer the best to patients”

Politicians who put anecdote before evidence do worry me quite a bit, I have to admit; by doing this, they provide us with strong evidence that they would be wise to keep their mouth shut when it comes to matters of science and medicine. But Hain is in good company: Jeremy Hunt (conservative), the current Secretary for Health, signed the following Early Day Motion in 2007: That this House welcomes the positive contribution made to the health of the nation by the NHS homeopathic hospitals; notes that some six million people use complementary treatments each year; believes that complementary medicine has the potential to offer clinically-effective and cost-effective solutions to common health problems faced by NHS patients, including chronic difficult to treat conditions such as musculoskeletal and other chronic pain, eczema, depression, anxiety and insomnia, allergy, chronic fatigue and irritable bowel syndrome; expresses concern that NHS cuts are threatening the future of these hospitals; and calls on the Government actively to support these valuable national assets.

The wording here is remarkable, I think: “…believes that complementary medicine has the potential to offer clinically-effective and cost-effective solutions to common health problems faced by NHS patients…” What is this supposed to mean? Health politics based on believe??? What it, in fact, implies is that there is merely belief but no evidence. Bravo! This looks like an own-goal to me.

And there are many, many more politicians who seem to prefer belief over evidence – not just in the UK but in virtually every country; our US friends would probably want me to mention Senator Tom Harkin who is responsible for spending billions of tax-payers’ dollars on researching implausible concepts with flawed studies. To make things worse, it is not just individual politicians who promote woo, as far as I can see, most political parties have a group of members promoting pseudo-science.

But why? Why do so many politicians misinform their voters about the values of unproven and disproven treatments? And I do not mean those members of parliament who nobody seems to be able to take seriously, like David Tredenick; I mean otherwise respectable politicians with real influence. Should they not be the first to insist on reliable evidence? Do they not have a mandate and an ethical/moral obligation to do so?

Call me cynical, but I have come to the conclusion that the answer is actually quite simple. Politicians need to be (re-)elected, and therefore they have to run with whatever subject is popular – and, like it or not, alternative medicine is popular. Politicians rarely take a reasonably long view on health care (in fact, very few understand the first thing about science or medicine); their perspective has exactly the same length as the current legislative period. They usually do not even attach much importance to alternative medicine; after all, it only amounts to a tiny fraction of the total health care budget.

Tony Blair (Labour) is as good an example as any other politician; in relation to homeopathy, he is quoted saying: I think that most people today have a rational view about science and my advice to the scientific community would be fight the battles you need to fight. I wouldn’t bother fighting a great battle over homeopathy – there are people who use it, people who don’t use it, it is not going to determine the future of the world, frankly. What will determine the future of the world however, is the scientific community explaining for example the science of genetics and how it develops, or the issue to do with climate change and so on.

Sounds reasonable? Almost, but not quite. Firstly, if people employ homeopathy to protect themselves from infectious diseases like malaria, typhus, TB, AIDS etc., or if people believe those charlatans who promote it as an effective cure for life-threatening conditions, we do have a serious public health issue at hand. Secondly, why should the vast majority of health care professionals bend over backwards to do their very best implementing the concepts of EBM, if homeopathy is being given a free ride to continue existing in a virtual universe of belief-based medicine? Thirdly, how on earth can scientists possibly explain “the science of genetics and how it develops, or the issue to do with climate change”, if they lack the skill, courage, power or honesty to adequately respond to harmful quackery masquerading as medicine?

It is not difficult to criticise politicians but what might be the way forward and out of this mess? Because of the central role they play in all this, I think that it would be important that those politicians who take up posts in science-based areas be adequately educated and trained in science. I know this may sound naïve, but I think it would be an essential step towards avoiding politicians regularly making fools of themselves, misinforming the public and misguiding important decisions which might affect all of us.

If my health insurance pays for this treatment, it must be scientifically tested and proven. The ‘appeal to authority’ is powerful indeed, and I imagine that many consumers fall for this argument. But it is a fallacy! Health insurances are misinforming us for commercial benefit.

In 2007, I published an analysis of German health insurance companies’ policies regarding bogus treatments (MMW 2006, 149: 55-56 [the paper is in German and unfortunately not Medline-listed]). For this purpose, I had selected three popular alternative modalities: Bach flower remedies, Schuessler salts, and kinesiology all of which are, of course, not supported by sound evidence nor by biological plausibility. What emerged from this evaluation was shocking: of the 13 companies analysed, 9 paid for Bach flower remedies, 7 for kinesiology and 9 for Schuessler salts.

If you now think ‘ah yes, those Germans are obsessed with alternative medicine’, think again. The situation in most other countries is not much better; health insurances go for alternative medicine as though there is no tomorrow. A review from the US concluded that the number of people using CAM insurance benefits was substantial; the effect on insurance expenditures was modest. Because the long-term trajectory of CAM cost under third-party payment is unknown, utilization of these services should be followed. And apparently this is by no means confined to human health; recently someone tweeted that he had a very hard time finding a pet-insurance which did not offer to cover woo.

A few years after the above-mentioned publication, I was invited to speak at an international meeting of health insurers. I told the delegates in no uncertain terms that most of what they were offering to their clients in terms of alternative medicine was either unproven or disproven. There was stunned silence during the official discussion period, and I asked myself whether I had impolitely embarrassed my hosts. Then came the tea break, and one high-level representative of an insurance company after the other came to me to chat. Essentially, they all said: “We are well aware of the facts and the evidence you reviewed in your lecture; most of these treatments are useless, of course. But we have to offer them to our customers because we need to be competitive.”

In other words, health insurers, who normally are keen to keep their costs down, do not mind to pay for treatments which they know are ineffective simply because they use it as some sort of an advertising gimmick. In doing so they say or imply that these treatments do work. I think this is not just wrong and short-sighted, it is unethical and it significantly contributes to the ‘sea of misinformation’.

The WHO is one of the most respected organisations in all of health care. It therefore might come as a surprise that it features in my series of institutions contributing to the ‘sea of misinformation’ in the area of alternative medicine. I have deliberately selected the WHO from many other organisations engaging in similarly misleading activities in order to show that even the most respectable bodies can have little enclaves of quackery hidden in their midst.

In 2006, the WHO invited Prince Charles to elaborate on his most bizarre concepts in relation to ‘integrated medicine’. He told the World Health Assembly in Geneva: “The proper mix of proven complementary, traditional and modern remedies, which emphasises the active participation of the patient, can help to create a powerful healing force in the world…Many of today’s complementary therapies are rooted in ancient traditions that intuitively understood the need to maintain balance and harmony with our minds, bodies and the natural world…Much of this knowledge, often based on oral traditions, is sadly being lost, yet orthodox medicine has so much to learn from it.” He urged countries across the globe to improve the health of their  populations through a more integrated approach to health care. What he failed to mention is the fact that integrating disproven therapies into our clinical routine, as proponents of ‘integrated medicine’ demonstrably do, will not render medicine better or more compassionate but worse and less evidence-based. Or as my more brash US friends often point out: adding cow pie to apple pie is no improvement.

For many years during the early 2000s, the WHO had also been working on a document that would have promoted homeopathy worldwide. They had convened a panel of ‘experts’ including the Queen’s homeopath Peter Fisher. They advocated using this disproven treatment for potentially deadly diseases such as malaria, childhood diarrhoea, or TB as an alternative to conventional medicine. I had been invited to comment on a draft version of this document, but judging from the second draft, my criticism had been totally ignored. Fortunately, the publication of this disastrous advice could be stopped through a concerted initiative of concerned scientists who protested and pointed out that the implementation of this nonsense would kill millions.

In 2003, the WHO had already published a very similar report: a long consensus document on acupuncture. It includes the following list of diseases, symptoms or conditions for which acupuncture has been proved-through controlled trials-to be an effective treatment:

Adverse reactions to radiotherapy and/or chemotherapy
Allergic rhinitis (including hay fever)
Biliary colic
Depression (including depressive neurosis and depression following stroke)
Dysentery, acute bacillary
Dysmenorrhoea, primary
Epigastralgia, acute (in peptic ulcer, acute and chronic gastritis, and gastrospasm)
Facial pain (including craniomandibular disorders)
Hypertension, essential
Hypotension, primary
Induction of labour
Knee pain
Low back pain
Malposition of fetus, correction of
Morning sickness
Nausea and vomiting
Neck pain
Pain in dentistry (including dental pain and temporomandibular dysfunction)
Periarthritis of shoulder
Postoperative pain
Renal colic
Rheumatoid arthritis

If we compare these claims to the reliable evidence on the subject, we find that the vast majority of these indications is not supported by sound data (a fuller discussion on the WHO report and its history can be found in our book TRICK OR TREATMENT…). So, how can any organisation as well-respected globally as the WHO arrive at such outrageously misleading conclusions? The recipe for achieving this is relatively simple and time-tested by many similarly reputable institutions:

  • One convenes a panel of ‘experts’ all or most of whom have a known preconceived opinion in the direction on has decided to go.
  • One allows this panel to work out their own methodology for arriving at the conclusion they desire.
  • One encourages cherry-picking of the data.
  • One omits a meaningful evaluation of the quality of the reviewed studies.
  • One prevents any type of critical assessment of the report such as peer-review by sceptics.
  • If criticism does emerge nevertheless, one ignores it.

I should stress again that the WHO is, on the whole, a very good and useful organisation. This is precisely why I chose it for this post. As long as it is big enough, ANY such institution is likely to contain a little niche where woo and anti-science flourishes. There are far too many examples to mention, e.g. NICE, the NIH, UK and other governments. And this is the reason we must be watchful. It is all to human to assume that information is reliable simply because it originates from an authoritative source; the appeal to authority is appealing, of course, but it also is fallacious!


Colonic irrigation is the alternative therapy of celebrities (and those who like to imitate them): they tend to use it for all sorts of ailments, predominantly for loosing weight. And it works! When they have paid for the session, they are relieved of some cash as well as of about half a kilo of body weight. By the time they wake up the next morning, the money is still gone, but the weight is back. This is a most effective method for getting rid of some £s, but NOT an effective way for shedding a few pounds.

 Numerous synonyms for colonic irrigation exist, e.g. colonic treatment, colon cleansing, rectal irrigation, colon therapy, colon hydrotherapy, colonic. The treatment is based on the ancient but obsolete theory of ‘autointoxication’, i.e. the body is  assumed to poison itself with, ‘autotoxins’ which, in turn, cause various illnesses. So, it is implausible and there is also no evidence to suggest it is effective. But this does not stop professional organisations to make claims which are good for business.

My analysis of the claims made by professional organisations of practitioners of colonic irrigation across the globe aimed at assessing the therapeutic claims made by these institutions. Six such organisations were identified, and the contents of their websites were studied. The results showed that all of the six organisations make therapeutic claims on their websites. Frequently mentioned themes are ‘detoxification’, normalisation of intestinal functions, treatment of inflammatory bowel diseases and body weight reduction. The claims are mostly confined to symptomatic improvements – but there are exceptions, e.g. prevention of bowel cancer or sorting out Irritable Bowel Syndrome ‘once and for all’ . Other therapeutic claims pertain to asthma, menstrual irregularities, circulatory disorders, skin problems, improvement in energy levels and no longer requiring pharmacotherapy. All these claims represent testable hypotheses.

The question therefore arises whether these hypotheses have been tested and, if so, what the results of such investigations suggest? The use of colonic irrigation by alternative practitioners for any indications is not supported by any sound evidence at all. There are simply no trials to show effectiveness. Even worse is the fact that, although touted as safe, colonic irrigation can lead to serious complications.

The conclusion is therefore simple: colonic irrigation is neither demonstrably effective nor safe, and the information supplied by its professional organisations is therefore a significant contributor to the sea of misinformation in the realm of alternative medicine.

The UK ‘Society of Homeopaths’ (SoH) is the largest professional organisation of UK non-doctor, so-called lay- homeopaths. On their website, the SoH made very specific claims about homeopathy; in particular, they listed conditions for which homeopathy had allegedly been proven to be effective. These claims have now thoroughly been debunked, and the evidence the SoH produced in support of their claims has been shown to be misleading, cherry-picked or misinterpreted.

I have no idea who conducted the above-named investigation and made a youtube video of it, but I think it is essentially correct and well worth watching. My own experiences with the SoH relate mainly to two encounters.

The first was a complaint I made about one of their high-ranking officers, Ralf Jeutter. He had been promotiong homeopathic vaccinations on his website (needless to stress, I think, that there is no evidence to support the notion that homeopathic vaccinations are effective). As I felt that the SoH dragged their feet pursuing my complaint, I had to send several reminders. Eventually, they considered it and concluded that Reuter had done nothing wrong. This, presumably, is the reason why, even today, he can state on his website that Homeopathy is used to help individuals in dealing better with kinds of infections such as leptospirosis, meningitis and cholera. All is fine, it seems as long as a disclaimer is added: Any information obtained here is not to be construed as medical OR legal advice. The decision to vaccinate and how you implement that decision is yours and yours alone. The evidence for the efficacy of homeopathic immunisation is ‘anecdotal’. That means it is based on individuals’ reports past and present.

My second encounter with the SoH relates to my 2010 analysis of the SoH code of ethics and their adherence to it. The code demanded that:


  • ‘all speculative theories will be stated as such and clearly distinguished’
  • ‘no advertising may be used which expressly or implicitly claims to cure named diseases’
  • ‘Advertising shall not be false, fraudulent, misleading, deceptive, extravagant or sensational.’

Encouraged by these assurances, I decided to study the websites of some members of the SoH, and soon discovered numerous and very obvious violations of the above-mentioned imperatives. In an attempt to find the root of these transgressions, I scrutinised the SoH’s own website where I found a multitude violations on all levels of the SoH’s own code of ethics. Many of the violations related to claims which were not supported by evidence. In other words, the largest professional UK organisation of lay- homeopaths misled the public in several rather devious ways:

  • they pretended to adhere to a code of ethics which forbids members to mislead the public
  • SoH -members nevertheless did mislead the public in ways that public health at risk
  • and they did so not least because the SoH followed exactly the same strategy
  • thus the SoH violated its own code of ethics to the detriment of public health.

My analysis was conducted a while ago, and some might hope that the SoH has stopped systematically misleading the public. This hope, however, is harshly disappointed when you watch the brand-new video entitled TESTING HOMEOPATHY mentioned above. As the SoH is about to celebrate 35 years of wisdom, courage, knowledge and prosperity, I do wonder whether this should not be 35 years of dangerously misleading the public.

What do you think?



A lengthy article posted by THE HOMEOPATHIC COLLEGE recently advocated treating cancer with homeopathy. Since I doubt that many readers access this publication, I take the liberty of reproducing here their (also fairly lengthy) CONCLUSIONS in full:

Laboratory studies in vitro and in vivo show that homeopathic drugs, in addition to having the capacity to reduce the size of tumors and to induce apoptosis, can induce protective and restorative effects. Additionally homeopathic treatment has shown effects when used as a complementary therapy for the effects of conventional cancer treatment. This confirms observations from our own clinical experience as well as that of others that when suitable remedies are selected according to individual indications as well as according to pathology and to cell-line indications and administered in the appropriate doses according to the standard principles of homeopathic posology, homeopathic treatment of cancer can be a highly effective therapy for all kinds of cancers and leukemia as well as for the harmful side effects of conventional treatment. More research is needed to corroborate these clinical observations.

Homeopathy over almost two decades of its existence has developed more than four hundred remedies for cancer treatment. Only a small fraction have been subjected to scientific study so far. More homeopathic remedies need to be studied to establish if they have any significant action in cancer. Undoubtedly the next big step in homeopathic cancer research must be multiple comprehensive double-blinded, placebo-controlled, randomized clinical trials. To assess the effect of homeopathic treatment in clinical settings, volunteer adult patients who prefer to try homeopathic treatment instead of conventional therapy could be recruited, especially in cases for which no conventional therapy has been shown to be effective.

Many of the researchers conducting studies — cited here but not discussed — on the growing interest in homeopathic cancer treatment have observed that patients are driving the demand for access to homeopathic and other alternative modes of cancer treatment. So long as existing cancer treatment is fraught with danger and low efficacy, it is urgent that the research on and the provision of quality homeopathic cancer treatment be made available for those who wish to try it.

When I report about nonsense like that, I find it hard not to go into a fuming rage. But doing that would not be very constructive – so let me instead highlight (in random order) eight simple techniques that seem to be so common when unsubstantiated claims are being promoted for alternative treatments:

1) cherry pick the data

2) use all sorts of ‘evidence’ regardless how flimsy or irrelevant it might be

3) give yourself the flair of being highly scientific and totally impartial

4) point out how dangerous and ineffective all the conventional treatments are

5) do not shy away from overt lies

6) do not forget to stress that the science is in full agreement with your exhaustive clinical experience

7) stress that patients want what you are offering

8) ignore the biological plausibility of the underlying concepts

Provided we adhere to these simple rules, we can convince the unsuspecting public of just about anything – even of the notion that homeopathy is a cure for cancer!

A single, tiny mosquito can make my life a misery. It can rob me of a night’s sleep and turn me into a frantic lunatic. But now there is a remedy that, according to its manufacturer, makes my mosquito-phobia a distant memory. Mosquito-maniacs like myself can finally breathe a sigh of relief!

According to the manufacturer’s web-site, Mozi-Q is formula to reduce the frequency of bites as well as the reactions that people have to bites. No more itching and big red bumps! No more smelly sprays or stinky coils…what a great ally for camping, golfing, hiking, biking. This could revolutionize the whole outdoor experience! Some of the product’s features include:

  • It works within 30 minutes of taking it.
  • There are no side effects.
  • It works on other bugs aside from mosquitoes like ticks and head lice.
  • Product can be taken every 3-5 hours starting right before you go outside.
  • There are no contraindications.
  • Homeopathic medicine is by definition non-toxic…

Mozi-Q is a formula containing five homeopathic remedies:

  • Staphysagria
  • Ledum palustre
  • Urtica urens
  • Cedron 
  • Grindelia

They are in low C and D potencies, thereby acting at the physical level for their common indication, to reduce the frequency and severity of insect bites….

I am sure that most readers will, by now, ask themselves: is there any good evidence for these claims? The manufacturer’s site is pretty affirmative:

In the ’60s a homeopath by the name of HR. Trexler studied Staphysagria for its effectiveness at preventing mosquito bites. In a study of 421 subjects over a 4 year period, he found this remedy to be 90% effective…We have tested this remedy in our clinic over four mosquito seasons and found the response from the public confirmatory of Trexler’s findings.

Sounds great? Yes, but it turns out that the Trexler trial did not test the mixture contained in Mozi-Q at all; it used just one of its ingredients. Moreover, it seemed to have lacked a control group and therefore constitutes no reliable evidence. And the manufacturer’s own tests? I don’t know, they tell us nothing about them.

At this stage, the mosquito-phobe is disappointed. It seems to me that this product is not supported by sound evidence – more trick than treatment.

And why would this important? Because some people like me might lose a bit of sleep? No! It is important because mosquitos, ticks and other insects transmit diseases, some of which can be deadly. If someone claims that there is a preparation which protects us from insect-bites, some consumers will inevitably trust this claim. And this would not just be unfortunate; it could be life-threatening.

Swiss chiropractors have just published a clinical trial to investigate outcomes of patients with radiculopathy due to cervical disk herniation (CDH). All patients had neck pain and dermatomal arm pain; sensory, motor, or reflex changes corresponding to the involved nerve root and at least one positive orthopaedic test for cervical radiculopathy were included. CDH was confirmed by magnetic resonance imaging. All patients received regular neck manipulations.

Baseline data included two pain numeric rating scales (NRSs), for neck and arm, and the Neck Disability Index (NDI). At two, four and twelve weeks after the initial consultation, patients were contacted by telephone, and the data for NDI, NRSs, and patient’s global impression of change were collected. High-velocity, low-amplitude thrusts were administered by experienced chiropractors. The proportion of patients reporting to feel “better” or “much better” on the patient’s global impression of change scale was calculated. Pre-treatment and post-treatment NRSs and NDIs were analysed.

Fifty patients were included. At two weeks, 55.3% were “improved,” 68.9% at four and 85.7% at twelve weeks. Statistically significant decreases in neck pain, arm pain, and NDI scores were noted at 1 and 3 months compared with baseline scores. 76.2% of all sub-acute/chronic patients were improved at 3 months.

The authors concluded that most patients in this study, including sub-acute/chronic patients, with symptomatic magnetic resonance imaging-confirmed CDH treated with spinal manipulative therapy, reported significant improvement with no adverse events.

In the presence of disc herniation, chiropractic manipulations have been described to cause serious complications. Some experts therefore believe that CDH is a contra-indication for spinal manipulation. The authors of this study imply, however, that it is not – on the contrary, they think it is an effective intervention for CDH.

One does not need to be a sceptic to notice that the basis for this assumption is less than solid. The study had no control group. This means that the observed effect could have been due to:

a placebo response,

the regression towards the mean,

the natural history of the condition,

concomitant treatments,

social desirability,

or other factors which have nothing to do with the chiropractic intervention per se.

And what about the interesting finding that no adverse-effects were noted? Does that mean that the treatment is safe? Sorry, but it most certainly does not! In order to generate reliable results about possibly rare complications, the study would have needed to include not 50 but well over 50 000 patients.

So what does the study really tell us? I have pondered over this question for some time and arrived at the following answer: NOTHING!

Is that a bit harsh? Well, perhaps yes. And I will revise my verdict slightly: the study does tell us something, after all – chiropractors tend to confuse research with the promotion of very doubtful concepts at the expense of their patients. I think, there is a name for this phenomenon: PSEUDO-SCIENCE.

Australian researchers wanted to know whether acupuncture is effective for alleviating the symptoms of fibromyalgia, a common painful condition for which no universally accepted treatment exists. For this purpose, they conducted a Cochrane review. After extensive literature searches, they identified 9 RCTs, extracted their data and assessed risk of bias.

The results show that all studies except one were at low risk of selection bias; five were at risk of selective reporting bias; two were subject to attrition bias (favouring acupuncture); three were subject to performance bias (favouring acupuncture) and one to detection bias (favouring acupuncture).

Three studies utilised electro-acupuncture (EA) and the remainder manual acupuncture (MA) without electrical stimulation.

Low quality evidence from one study (13 participants) showed EA improved symptoms with no adverse events at one month following treatment.

Moderate quality evidence from six studies (286 participants) indicated that acupuncture (EA or MA) was no better than sham acupuncture, except for less stiffness at one month. Subgroup analysis of two studies (104 participants) indicated benefits of EA. Mean pain was 70 points on 0 to 100 point scale with sham treatment; EA reduced pain by 13% (5% to 22%).

Low-quality evidence from one study suggested that MA resulted in poorer physical function: mean function in the sham group was 28 points (100 point scale); treatment worsened function by a mean of 6 points.

Moderate quality evidence from one study (58 participants) found that, compared with standard therapy alone (antidepressants and exercise), adjunct acupuncture therapy reduced pain at one month after treatment.

Low quality evidence from one study (38 participants) showed a short-term benefit of acupuncture over antidepressants in pain relief.

Moderate-quality evidence from one study (41 participants) indicated that deep needling with or without deqi did not differ in pain, fatigue, function or adverse events.

Four studies reported no differences between acupuncture and control or other treatments described at six to seven months follow-up.

No serious adverse events were reported, but there were insufficient adverse events to be certain of the risks.

The authors draw the following conclusions: There is low to moderate-level evidence that compared with no treatment and standard therapy, acupuncture improves pain and stiffness in people with fibromyalgia. There is moderate-level evidence that the effect of acupuncture does not differ from sham acupuncture in reducing pain or fatigue, or improving sleep or global well-being. EA is probably better than MA for pain and stiffness reduction and improvement of global well-being, sleep and fatigue. The effect lasts up to one month, but is not maintained at six months follow-up. MA probably does not improve pain or physical functioning. Acupuncture appears safe. People with fibromyalgia may consider using EA alone or with exercise and medication. The small sample size, scarcity of studies for each comparison, lack of an ideal sham acupuncture weaken the level of evidence and its clinical implications. Larger studies are warranted.

What does all that mean? In my view, it means that there is no sound evidence base for acupuncture as a treatment of fibromyalgia – or as we expressed it in our own systematic review of 2007: The notion that acupuncture is an effective symptomatic treatment for fibromyaligia is not supported by the results from rigorous clinical trials. On the basis of this evidence, acupuncture cannot be recommended for fibromyalgia.

In a recent comment, US chiropractors stated that there is a growing recognition within the profession that the practicing chiropractor must be able to do the following: formulate a searchable clinical question, rapidly access the best evidence available, assess the quality of that evidence, determine if it is applicable to a particular patient or group of patients, and decide if and how to incorporate the evidence into the care being offered. In a word, they believe, that evidence-based chiropractic is possible, perhaps even (almost) a reality. For evidence-based practice to penetrate and transform a profession, the penetration must occur at two levels, they explain. One level is the degree to which individual practitioners possess the willingness and basic skills to search and assess the literature.

The second level, the authors explain, relates to whether the therapeutic interventions commonly employed by a particular health care discipline are supported by clinical research. The authors believe that a growing body of randomized controlled trials provides evidence of the effectiveness and safety of manual therapies. Is this really true, I wonder.

In support of these fairly bold statements, they cite a paper by Bronfort et al which, in their view, is currently the most comprehensive review of the evidence for the efficacy of manual therapies. According to these authors, the ‘Bronfort-report’ stated that evidence is inconclusive for pneumonia, stage 1 hypertension, pre-menstrual syndrome, nocturnal enuresis, and otitis media. The authors also believe that it is unlikely manipulation of the neck is causally related to stroke.

When I read this article, I could not stop myself from giggling. It seems to me that it provides pretty good evidence for the fact that the chiropractic profession is nowhere near reaching the stage where anyone could reasonably claim that chiropractors practice evidence-based medicine – not even the authors themselves seem to abide by the rules of evidence-based medicine! If they had truly been able to access the best evidence available and assess the quality of that evidence surely they would not have (mis-) quoted the ‘Bronfort-report’.

Bronfort’s overview was commissioned by the General Chiropractic Council, it was hastily compiled by ardent believers of chiropractic, published in a journal that non-chiropractors would not touch with a barge pole, and crucially it lacks some of the most important qualities of an unbiased systematic review. In my view, it is nothing short of a white-wash and not worth the paper it was printed on. Conclusions, such as the evidence regarding pneumonia, bed-wetting and otitis is inconclusive are just embarrassing; the correct conclusion is that the evidence fails to be positive for these and most other indications.

Similarly, if the authors had really studied and quoted the best evidence, how on earth could they have stated that manipulation of the neck cannot cause a stroke? The evidence for that is fairly overwhelming, and the only open question here is, how often do such complications occur? And even the biased ‘Bronfort-report’ states: Adverse events associated with manual treatment can be classified into two categories: 1) benign, minor or non-serious and 2) serious. Generally those that are benign are transient, mild to moderate in intensity, have little effect on activities, and are short lasting. Most commonly, these involve pain or discomfort to the musculoskeletal system. Less commonly, nausea, dizziness or tiredness are reported. Serious adverse events are disabling, require hospitalization and may be life-threatening. The most documented and discussed serious adverse event associated with spinal manipulation (specifically to the cervical spine) is vertebrobasilar artery (VBA) stroke. Less commonly reported are serious adverse events associated with lumbar spine manipulation, including lumbar disc herniation and cauda equina syndrome.

Evidence-based practice? Who are these chiropractors kidding? This article very neatly reflects the exact opposite. It ignores hundreds of peer-reviewed papers which are critical of chiropractic. The best one can do with this paper, I think, is to use it as a hilarious bit of involuntary humour or as a classic example of cherry-picking.

Come to think of it, chiropractic and evidence-based practice are contradictions in terms. Either a therapist claims to adjust mystical subluxations, in which case he/she does not practice evidence-based medicine. Or he/she practices evidence-based medicine, in which case adjusting mystical subluxations cannot be part of their therapeutic repertoire.

Towards the end of the article, we learn further fascinating things: the authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article – oh, really?!?! Furthermore, we are told that this ‘research’ was funded by the ‘National Center of Complementary and Alternative Medicine’ (NCCAM) of the National Institutes of Health.

Can it be true? Does the otherwise most respectable NIH really give its name for such overt nonsense? Yes, it is true, and it is by no means the first time. In fact, our analysis shows that, when it comes to chiropractic, this organisation has sponsored almost nothing but utter rubbish, and our conclusion was blunt: the criticism repeatedly aimed at NCCAM seems justified, as far as their RCTs of chiropractic is concerned. It seems questionable whether such research is worthwhile.
