The Spanish Ministries of Health and Sciences have announced their ‘Health Protection Plan against Pseudotherapies’. Very wisely, they have included chiropractic under this umbrella. To a large degree, this is the result of Spanish sceptics pointing out that alternative therapies are a danger to public health, helped perhaps a tiny bit also by the publication of two of my books (see here and here) in Spanish. Unsurprisingly, such delelopments alarm Spanish chiropractors who fear for their livelihoods. A quickly-written statement of the AEQ (Spanish Chiropractic Association) is aimed at averting the blow. It makes the following 11 points (my comments are below):
1. The World Health Organization (WHO) defines chiropractic as a healthcare profession. It is independent of any other health profession and it is neither a therapy nor a pseudotherapy.
2. Chiropractic is statutorily recognised as a healthcare profession in many European countries including Portugal, France, Italy, Switzerland, Belgium, Denmark, Sweden, Norway and the United Kingdom10, as well as in the USA, Canada and Australia, to name a few.
3. Chiropractic members of the AEQ undergo university-level training of at least 5 years full-time (300 ECTS points). Chiropractic training is offered within prestigious institutions such as the Medical Colleges of the University of Zurich and the University of Southern Denmark.
4. Chiropractors are spinal health care experts. Chiropractors practice evidence-based, patient-centred conservative interventions, which include spinal manipulation, exercise prescription, patient education and lifestyle advice.
5. The use of these interventions for the treatment of spine-related disorders is consistent with guidelines and is supported by high quality scientific evidence, including multiple systematic reviews undertaken by the prestigious Cochrane collaboration15, 16, 17.
6. The Global Burden of Disease study shows that spinal disorders are the leading cause of years lived with disability worldwide, exceeding depression, breast cancer and diabetes.
7. Interventions used by chiropractors are recommended in the 2018 Low Back Pain series of articles published in The Lancet and clinical practice guidelines from Denmark, Canada, the European Spine Journal, American College of Physicians and the Global Spine Care Initiative.
8. The AEQ supports and promotes scientific research, providing funding and resources for the development of high quality research in collaboration with institutions of high repute, such as Fundación Jiménez Díaz and the University of Alcalá de Henares.
9. The AEQ strenuously promotes among its members the practice of evidence-based, patient-centred care, consistent with a biopsychosocial model of health.
10. The AEQ demands the highest standards of practice and professional ethics, by implementing among its members the Quality Standard UNE-EN 16224 “Healthcare provision by chiropractors”, issued by the European Committee of Normalisation and ratified by AENOR.
11. The AEQ urges the Spanish Government to regulate chiropractic as a healthcare profession. Without such legislation, citizens of Spain cannot be assured that they are protected from unqualified practitioners and will continue to face legal uncertainties and barriers to access an essential, high-quality, evidence-based healthcare service.
END OF QUOTE
I think that some comments might be in order (they follow the numbering of the AEQ):
- The WHO is the last organisation I would consult for information on alternative medicine; during recent years, they have published mainly nonsense on this subject. How about asking the inventor of chiropractic? D.D. Palmer defined it as “a science of healing without drugs.” Chiropractors nowadays prefer to be defined as a profession which has the advantage that one cannot easily pin them down for doing mainly spinal manipulation; if one does, they indignantly respond “but we also use many other interventions, like life-style advice, for instance, and nobody can claim this to be nonsense” (see also point 4 below).
- Perfect use of a classical fallacy: appeal to authority.
- Appeal to authority, plus ignorance of the fact that teaching nonsense even at the highest level must result in nonsense.
- This is an ingenious mix of misleading arguments and lies: most chiros pride themselves of treating also non-spinal conditions. Very few interventions used by chiros are evidence-based. Exercise prescription, patient education and lifestyle advice are hardy typical for chiros and can all be obtained more authoratively from other healthcare professionals.
- Plenty of porkies here too. For instance, the AEQ cite three Cochrane reviews. The first concluded that high-quality evidence suggests that there is no clinically relevant difference between SMT and other interventions for reducing pain and improving function in patients with chronic low-back pain. The second stated that combined chiropractic interventions slightly improved pain and disability in the short term and pain in the medium term for acute/subacute LBP. However, there is currently no evidence that supports or refutes that these interventions provide a clinically meaningful difference for pain or disability in people with LBP when compared to other interventions. And the third concluded that, although support can be found for use of thoracic manipulation versus control for neck pain, function and QoL, results for cervical manipulation and mobilisation versus control are few and diverse. Publication bias cannot be ruled out. Research designed to protect against various biases is needed. Findings suggest that manipulation and mobilisation present similar results for every outcome at immediate/short/intermediate-term follow-up. Multiple cervical manipulation sessions may provide better pain relief and functional improvement than certain medications at immediate/intermediate/long-term follow-up. Since the risk of rare but serious adverse events for manipulation exists, further high-quality research focusing on mobilisation and comparing mobilisation or manipulation versus other treatment options is needed to guide clinicians in their optimal treatment choices. Hardly the positive endorsement implied by the AEQ!
- Yes, but that is not an argument for chiropractic; in fact, it’s another fallacy.
- Did they forget the many guidelines, institutions and articles that do NOT recommend chiropractic?
- I believe the cigarette industry also sponsors research; should we therefore all start smoking?
- I truly doubt that the AEQ strenuously promotes among its members the practice of evidence-based healthcare; if they did, they would have to discourage spinal manipulation!
- The ‘highest standards of practice and professional ethics’ are clearly not compatible with chiropractors’ use of spinal manipulation. In our recent book, we explained in full detail why this is so.
- An essential, high-quality, evidence-based healthcare service? Chiropractic is certainly not essential, rarely high-quality, and clearly not evidence-based.
Nice try AEQ.
But not good enough, I am afraid.
It is time, I think, to express my gratitude to Dr Jens Behnke, a German homeopath employed by the pro-homeopathy lobby group the ‘Carstens Stiftung’, who diligently tweets trials of homeopathy which he obviously believes prove the value of his convictions.
The primary objective of this new study was to evaluate the efficacy of homoeopathy for women suffering from polycystic ovary syndrome. This condition is characterised by:
- irregular periods which means your ovaries don’t regularly release eggs,
- abnormally high levels of male hormones in the body, which may cause physical signs such as excess facial or body hair,
- polycystic ovaries – ovaries become enlarged and contain many fluid-filled sacs (follicles) which surround the eggs.
There’s no cure for PCOS, but the symptoms can usually be treated. As so often in such situations, homeopaths are happy to step into the fray.
This single-blind, randomised, placebo-controlled pilot study was conducted at two research centres in India. The cases fulfilling the eligibility criteria were enrolled (n = 60) and randomised to either the homoeopathic intervention (HI) (n = 30) or placebo (P) (n = 30) with uniform lifestyle modification (LSM) for 6 months.
The menstrual regularity with improvement in other signs/symptoms was observed in 60% of the cases (n = 18) in HI + LSM group and none (n = 0) in control group. Statistically significant difference was observed in the reduction of intermenstrual duration in HI + LSM in comparison to placebo + LSM group. Significant improvements were also observed in HI+LSM group in domains of weight, fertility, emotions and menstrual problems. No change was observed in respect of improvement in the ultrasound findings. Pulsatilla was the most frequently indicated homeopathic remedy.
The authors concluded that HI along with LSM has shown promising outcome; further comparative study with standard conventional treatment on adequate sample size is desirable.
This trial might convince believers (mostly because they do not even need convincing), but it cannot convince anybody capable of critical thinking. Here is why:
- According to its authors, this trial was a pilot study; this means it should not report any results and merely focus on the feasibility of a definitive trial.
- Researchers were not blinded, meaning that they might have influenced the outcome in more than one way.
- The primary endpoint was subjective and could have been influenced by the non-blinded researchers.
- 0% success rate in achieving the primary endpoint in the placebo group is not plausible.
- Compliance to LSM was not checked; as the homeopathy group lost more weight, these patients seemed to have complied better (probably due to being better motivated by the non-blinded researchers).
My conclusion is not very original but all the more true: POORLY DESIGNED STUDIES USUALLY GENERATE UNRELIABLE RESULTS.
Ginkgo biloba is a well-researched herbal medicine which has shown promise for a number of indications. But does this include coronary heart disease?
The aim of this systematic review was to provide information about the effectiveness and safety of Ginkgo Leaf Extract and Dipyridamole Injection (GD) as one adjuvant therapy for treating angina pectoris (AP) and to evaluate the relevant randomized controlled trials (RCTs) with meta-analysis. (Ginkgo Leaf Extract and Dipyridamole Injection is a Chinese compound preparation, which consists of ginkgo ﬂavone glycosides (24%), terpene lactones (ginkgolide about 13%, ginkgolide about 2.9%) and dipyridamole.)
RCTs concerning AP treated by GD were searched and the Cochrane Risk Assessment Tool was adopted to assess the methodological quality of the RCTs. A total of 41 RCTs involving 4,462 patients were included in the meta-analysis. The results indicated that the combined use of GD and Western medicine (WM) against AP was associated with a higher total effective rate [risk ratio (RR)=1.25, 95% confidence interval (CI): 1.21–1.29, P<0.01], total effective rate of electrocardiogram (RR=1.29, 95% CI: 1.21–1.36, P<0.01). Additional, GD combined with WM could decrease the level of plasma viscosity [mean difference (MD)=–0.56, 95% CI:–0,81 to–0.30, P<0.01], fibrinogen [MD=–1.02, 95% CI:–1.50 to–0.54, P<0.01], whole blood low shear viscosity [MD=–2.27, 95% CI:–3.04 to–1.49, P<0.01], and whole blood high shear viscosity (MD=–0.90, 95% CI: 1.37 to–0.44, P<0.01).
The authors concluded that comparing with receiving WM only, the combine use of GD and WM was associated with a better curative effect for patients with AP. Nevertheless, limited by the methodological quality of included RCTs more large-sample, multi-center RCTs were needed to confirm our findings and provide further evidence for the clinical utility of GD.
If one reads this conclusion, one might be tempted to use GD to cure AP. I would, however, strongly warn everyone from doing so. There are many reasons for my caution:
- All the 41 RCTs originate from China, and we have repeatedly discussed that Chinese TCM trials are highly unreliable.
- The methodological quality of the primary RCTs was, according to the review authors ‘moderate’. This is not true; it was, in fact, lousy.
- Dipyridamole is not indicated in angina pectoris.
- To the best of my knowledge, there is no good evidence from outside China to suggest that Ginkgo biloba is effective for angina pectoris.
- Angina pectoris is caused by coronary artery disease (a narrowing of one or more coronary arteries due to atherosclerosis), and it seems implausible that this condition can be ‘cured’ with any medication.
So, what we have here is yet another nonsensical paper, published in a dubious journal, employing evidently irresponsible reviewers, run by evidently irresponsible editors, hosted by a seemingly reputable publisher (Springer). This is reminiscent of my previous post (and many posts before). Alarmingly, it is also what I encounter on a daily basis when scanning the new publications in my field.
The effects of this incessant stream of nonsense can only have one of two effects:
- People take this ‘evidence’ seriously. In this case, many patients might pay with their lives for this collective incompetence.
- People conclude that alt med research cannot be taken seriously. In this case, we are unlikely to ever see anything useful emerging from it.
Either way, the result will be profoundly negative!
It is high time to stop this idiocy; but how?
I wish, I knew the answer.
Shiatsu has been mentioned here before (see for instance here, here and here). It is one of those alternative therapies for which a plethora of therapeutic claims are being made in the almost total absence of reliable evidence. This is why I am delighted each time a new study emerges.
This proof of concept study explored the feasibility of ‘hand self-shiatsu’ as an intervention to promote sleep onset and continuity for young adults with SRC. It employed a prospective case-series design, where participants, athletes who have suffered from concussion, act as their own controls. Baseline and follow-up data included standardized self-reported assessment tools and sleep actigraphy. Seven athletes, aged between 18 and 25 years, participated. Although statistically significant improvement in actigraphy sleep scores between baseline and follow-up was not achieved, metrics for sleep quality and daytime fatigue showed significant improvement.
The authors concluded from these data that these findings support the hypothesis that ‘hand self-shiatsu has the potential to improve sleep and reduce daytime fatigue in young postconcussion athletes. This pilot study provides guidance to refine research protocols and lays a foundation for further, large-sample, controlled studies.
How very disappointing! If this was truly meant to be a pilot study, it should not mention findings of clinical improvement at all. I suspect that the authors labelled it ‘a pilot study’ only when they realised that it was wholly inadequate. I also suspect that the study did not yield the result they had hoped for (a significant improvement in actigraphy sleep scores), and thus they included the metrics for sleep quality and daytime fatigue in the abstract.
In any case, even a pilot study of just 7 patients is hardly worth writing home about. And the remark that participants acted as their own controls is a new level of obfuscation: there were no controls, and the results are based on before/after comparisons. Thus none of the outcomes can be attributed to shiatsu; more likely, they are due to the natural history of the condition, placebo effects, concomitant treatments, social desirability etc.
What sort of journal publishes such drivel that can only have the effect of giving a bad name to clinical research? The Journal of Integrative Medicine (JIM) is a peer-reviewed journal sponsored by Shanghai Association of Integrative Medicine and Shanghai Changhai Hospital, China. It is a continuation of the Journal of Chinese Integrative Medicine (JCIM), which was established in 2003 and published in Chinese language. Since 2013, JIM has been published in English language. They state that the editorial board is committed to publishing high-quality papers on integrative medicine... I consider this as a bad joke! More likely, this journal is little more than an organ for popularising TCM propaganda in the West.
And which publisher hosts such a journal?
What a disgrace!
This systematic review was aimed at evaluating the effects of acupuncture on the quality of life of migraineurs. Only randomized controlled trials that were published in Chinese and English were included. In total, 62 trials were included for the final analysis; 50 trials were from China, 3 from Brazil, 3 from Germany, 2 from Italy and the rest came from Iran, Israel, Australia and Sweden.
Acupuncture resulted in lower Visual Analog Scale scores than medication at 1 month after treatment and 1-3 months after treatment. Compared with sham acupuncture, acupuncture resulted in lower Visual Analog Scale scores at 1 month after treatment.
The authors concluded that acupuncture exhibits certain efficacy both in the treatment and prevention of migraines, which is superior to no treatment, sham acupuncture and medication. Further, acupuncture enhanced the quality of life more than did medication.
The authors comment in the discussion section that the overall quality of the evidence for most outcomes was of low to moderate quality. Reasons for diminished quality consist of the following: no mentioned or inadequate allocation concealment, great probability of reporting bias, study heterogeneity, sub-standard sample size, and dropout without analysis.
Further worrisome deficits are that only 14 of the 62 studies reported adverse effects (this means that 48 RCTs violated research ethics!) and that there was a high level of publication bias indicating that negative studies had remained unpublished. However, the most serious concern is the fact that 50 of the 62 trials originated from China, in my view. As I have often pointed out, such studies have to be categorised as highly unreliable.
In view of this multitude of serious problems, I feel that the conclusions of this review must be re-formulated:
Despite the fact that many RCTs have been published, the effect of acupuncture on the quality of life of migraineurs remains unproven.
I only recently came across this review; it was published a few years ago but is still highly relevant. It summarizes the evidence of controlled clinical studies of TCM for cancer.
The authors searched all the controlled clinical studies of TCM therapies for all kinds of cancers published in Chinese in four main Chinese electronic databases from their inception to November 2011. They found a total of 2964 reports (involving 253,434 cancer patients) including 2385 randomized controlled trials and 579 non-randomized controlled studies.
The top seven cancer types treated were lung cancer, liver cancer, stomach cancer, breast cancer, esophagus cancer, colorectal cancer and nasopharyngeal cancer by both study numbers and case numbers. The majority of studies (72%) applied TCM therapy combined with conventional treatment, whilst fewer (28%) applied only TCM therapy in the experimental groups. Herbal medicine was the most frequently applied TCM therapy (2677 studies, 90.32%). The most frequently reported outcome was clinical symptom improvement (1667 studies, 56.24%) followed by biomarker indices (1270 studies, 42.85%), quality of life (1129 studies, 38.09%), chemo/radiotherapy induced side effects (1094 studies, 36.91%), tumour size (869 studies, 29.32%) and safety (547 studies, 18.45%).
The authors concluded that data from controlled clinical studies of TCM therapies in cancer treatment is substantial, and different therapies are applied either as monotherapy or in combination with conventional medicine. Reporting of controlled clinical studies should be improved based on the CONSORT and TREND Statements in future. Further studies should address the most frequently used TCM therapy for common cancers and outcome measures should address survival, relapse/metastasis and quality of life.
This paper is important, in my view, predominantly because it exemplifies the problem with TCM research from China and with uncritical reviews on this subject. If a cancer patient, who does not know the background, reads this paper, (s)he might think that TCM is worth trying. This conclusion could easily shorten his/her life.
The often-shown fact is that TCM studies from China are not reliable. They are almost invariably positive, their methodological quality is low, and they are frequently based on fabricated data. In my view, it is irresponsible to publish a review that omits discussing these facts in detail and issuing a stark warning.
TCM FOR CANCER IS A VERY BAD CHOICE!

A survey was commissioned in 2015 to obtain general population figures for practitioner-led CAM use in England, and to discover people’s views and experiences regarding access.
Of 4862 adults surveyed, 766 (16%) had seen a CAM practitioner. People most commonly visited CAM practitioners for manual therapies (massage, osteopathy, chiropractic) and acupuncture, as well as yoga, pilates, reflexology, and mindfulness or meditation. Women, people with higher socioeconomic status (SES) and those in south England were more likely to access CAM. Musculoskeletal conditions (mainly back pain) accounted for 68% of use, and mental health 12%. Most was through self-referral (70%) and self-financing. GPs (17%) or NHS professionals (4%) referred and/or recommended CAM to users. These CAM users were more often unemployed, with lower income and social grade, and receiving NHS-funded CAM. Responders were willing to pay varying amounts for CAM; 22% would not pay anything. Almost two in five responders felt NHS funding and GP referral and/or endorsement would increase their CAM use.
The authors concluded that CAM use in England is common for musculoskeletal and mental health problems, but varies by sex, geography, and SES. It is mainly self-referred and self-financed; some is GP-endorsed and/or referred, especially for individuals of lower SES. Researchers, patients, and commissioners should collaborate to research the effectiveness and cost-effectiveness of CAM and consider its availability on the NHS.
The table below shows the percentage figures for specific CAMs (right column).
|Type of CAM practitioner||n||%|
|Meditation and/or mindfulness teacher||20||3|
|Chinese herbal medical practitioner||12||2|
Our own survey suggested that, in 2005, the 1-year prevalence of CAM-use in England was 26.3 % and the practitioner-led CAM-use was 12.1 %. The two surveys are, however, not comparable because they did use different methodologies; for instance, they included different types of CAM. I therefore think that any conclusion of an increase in practitioner-led CAM-use between 2005 and 2015 is not warranted. It also follows that the graphic below is misleading.
In the discussion, the authors of the new survey make the following point: Ability to pay may be a factor in accessing CAM (indicated by the association of CAM use with higher SES; lower SES responders being more likely to be GP-referred to CAM; and responders stating that they may use more CAM if the NHS provided services, and GPs endorsed and/or referred them). Integration of CAM into the NHS through primary care could promote continuity of care, safety, and balance of power. An integrative medicine approach includes many of the values recently included in UK health policy documents; for example, Five Year Forward View. It is patient-centred, as discussed in 2010, focuses on prevention, and emphasises patient self-management and person- and community-centred approaches to health and wellbeing. Many of these values underpin social prescribing, which is an increasingly popular model of health care. There seems to be significant patient demand for CAM and more holistic approaches, and a view that CAM may improve patient satisfaction.
I have in a previous post commented on prevalence surveys: the argument that is all too often spun around such survey data goes roughly as follows: a large percentage of the population uses alternative medicine; people pay out of their own pocket for these treatments; they are satisfied with them (if not, they would not pay for them). BUT THIS IS GROSSLY UNFAIR! Why should only those individuals who are rich enough to afford alternative medicine benefit from it? ALTERNATIVE MEDICINE SHOULD BE MADE AVAILABLE FOR ALL.
To me, it is obvious that this line of argument is dangerously wrong. It lends itself to the promotion of unproven therapies to the detriment of good healthcare and progress. Sadly, I fear that the new survey is going to be misused in this way.
Yesterday was the 80th anniversary of the Kristallnacht, the infamous start of the Nazi holocaust. For Cristian Becker, a German PR man who is currently spending much of his time promoting homeopathy and attacking critics of homeopathy, it was the occasion to publish this tweet:
Today, on 9 November, all fundamentalist GWUP-sceptics such as Natalie Grams and Edzard Ernst reflect on what hate can bring about. First, one hates homeopathy, then advocates of homeopathy, and then it can seem as though one tolerates violence.
I struggle to respond to such vitriolic stupidity.
What makes this even more shocking is the fact that, as far as I see, none of the professional bodies of German homeopathy have distanced themselves for it.
I know Dr Grams a little, and can honestly say that neither of us ‘hates’ homeopathy nor homeopaths. And crucially, we both detest violence.
If such pseudo-arguments are now being used by the defenders of homeopathy, it mainly shows, I think, two things:
- They clearly have run out of real arguments which, in turn, suggests that the end of publicly funded homeopathy is imminent.
- Homeopathic remedies are not an effective therapy against feeble-mindedness.
The Clinic for Complementary Medicine and Diet in Oncology was opened, in collaboration with the oncology department, at the Hospital of Lucca (Italy) in 2013. It uses a range of alternative therapies aimed at reducing the adverse effects of conventional oncology treatments.
Their latest paper presents the results of complementary medicine (CM) treatment targeted toward reducing the adverse effects of anticancer therapy and cancer symptoms, and improving patient quality of life. Dietary advice was aimed at the reduction of foods that promote inflammation in favour of those with antioxidant and anti-inflammatory properties.
This is a retrospective observational study on 357 patients consecutively visited from September 2013 to December 2017. The intensity of symptoms was evaluated according to a grading system from G0 (absent) to G1 (slight), G2 (moderate), and G3 (strong). The severity of radiodermatitis was evaluated with the Radiation Therapy Oncology Group (RTOG) scale. Almost all the patients (91.6%) were receiving or had just finished some form of conventional anticancer therapy.
The main types of cancer were breast (57.1%), colon (7.3%), lung (5.0%), ovary (3.9%), stomach (2.5%), prostate (2.2%), and uterus (2.5%). Comparison of clinical conditions before and after treatment showed a significant amelioration of all symptoms evaluated: nausea, insomnia, depression, anxiety, fatigue, mucositis, hot flashes, joint pain, dysgeusia, neuropathy.
The authors concluded that the integration of evidence-based complementary treatments seems to provide an effective response to cancer patients’ demand for a reduction of the adverse effects of anticancer treatments and the symptoms of cancer itself, thus improving patient’s quality of life and combining safety and equity of access within public healthcare systems. It is, therefore, necessary for physicians (primarily oncologists) and other healthcare professionals in this ﬁeld to be appropriately informed about the potential beneﬁts of CMs.
Why do I call this ‘wishful thinking’?
I have several reasons:
- A retrospective observational study cannot establish cause and effect. It is likely that the findings were due to a range of factors unrelated to the interventions used, including time, extra attention, placebo, social desirability, etc.
- Some of the treatments in the therapeutic package were not CM, reasonable and evidence-based. Therefore, it is likely that these interventions had positive effects, while CM might have been totally useless.
- To claim that the integration of evidence-based complementary treatments seems to provide an effective response to cancer patients’ is pure fantasy. Firstly, some of the CMs were certainly not evidence-based (the clinic’s prime focus is on homeopathy). Secondly, as already pointed out, the study does not establish cause and effect.
- The notion that it is necessary for physicians (primarily oncologists) and other healthcare professionals in this ﬁeld to be appropriately informed about the potential beneﬁts of CMs is not what follows from the data. The paper shows, however, that the authors of this study are in need to be appropriately informed about EBM as well as CM.
I stumbled across this paper because a homeopath cited it on Twitter claiming that it proves the effectiveness of homeopathy for cancer patients. This fact highlights why such publications are not just annoyingly useless but acutely dangerous. They mislead many cancer patients to opt for bogus treatments. In turn, this demonstrates why it is important to counterbalance such misinformation, critically evaluate it and minimise the risk of patients getting harmed.
