Back pain is a huge problem: it affects many people, causes much suffering and leads to extraordinary high cost for all of us. Considering these facts, it would be excellent to identify a treatment that truly works. However, at present, we do not have found the ideal therapy; instead we have dozens of different approaches that are similarly effective/ineffective. Two of these therapies are massage and acupuncture.
Is one better than the other?
This study compared the efficacy of classical massage (KMT, n = 66) with acupuncture therapy (AKU, n = 66) in patients with chronic back pain. The primary endpoint was the non-inferiority of classical massage compared with the acupuncture treatment in respect of the impairment in everyday life, with the help of the Hannover function questionnaire (HFAQ) and the reduction in pain (“Von Korff”-Questionnaire) at the follow-up after one month.
In the per-protocol analysis during the period between enrollment in the study and follow-up, the responder rate of the KMT was 56.5% and thus tended to be inferior to the responder rate of the AKU with 62.5% (Δ = - 6%; KIΔ: - 23.5 to + 11.4%).
The authors concluded that classical massage therapy is not significantly inferior to acupuncture therapy in the period from admission to follow-up. Thus, the non-inferiority of the KMT to the AKU cannot be proven in the context of the defined irrelevance area.
I find such studies oddly useless.
To conduct a controlled trial, one needs an experimental treatment (the therapy that is not understood) and compare it with an intervention that is understood (such as a placebo that has no specific effects, or a treatment that has been shown to work). In comparative studies like the one above, one compares one unknown with another unknown. I do not see how such a comparison can ever produce a meaningful result.
In a way, it is like an equation with two unknowns: x + 5 = y. It is simply not possible to define either x nor y, and the equation is unsolvable.
For comparative studies of two back-pain treatments to make sense, we would need one of which the effect size is well-established. I do not think that we currently have identified such a therapy. Certainly, we cannot say that we know it for massage or acupuncture.
In other words, comparative studies like the one above are a waste of resources that cannot possibly make a meaningful contribution to our knowledge.
To put it even more bluntly: we ought to stop such pseudo-research.
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.
Acupuncture is a branch of alternative medicine where pseudo-science abounds. Here is yet another example of this deplorable phenomenon.
This study was conducted to evaluate the efficacy of acupuncture in the management of primary dysmenorrhea.
Sixty females aged 17-23 years were randomly assigned to either a study group or a control group.
- The study group received acupuncture for the duration of 20 minutes/day, for 15 days/month, for the period of 90 days.
- The control group did not receive acupuncture for the same period.
Both groups were assessed on day 1; day 30 and day 60; and day 90. The results showed a significant reduction in all the variables such as the visual analogue scale score for pain, menstrual cramps, headache, dizziness, diarrhoea, faint, mood changes, tiredness, nausea, and vomiting in the study group compared with those in the control group.
The authors concluded that acupuncture could be considered as an effective treatment modality for the management of primary dysmenorrhea.
These findings contradict those of a recent Cochrane review (authored by known acupuncture-proponents) which included 42 RCTs and concluded that there is insufficient evidence to demonstrate whether or not acupuncture or acupressure are effective in treating primary dysmenorrhoea, and for most comparisons no data were available on adverse events. The quality of the evidence was low or very low for all comparisons. The main limitations were risk of bias, poor reporting, inconsistency and risk of publication bias.
The question that I ask myself is this: why do researchers bother to conduct studies that contribute NOTHING to our knowledge and progress? The new study had a no-treatment control group which means it cannot control for the effects of placebo, the extra attention, social desirability etc. In view of the fact that already 42 poor quality trials exist, it is not just useless to add a 43rd but, in my view, it is scandalous! A 43rd useless trial:
- tells us nothing of value;
- misleads the public;
- pollutes the medical literature;
- is a waste of resources;
- undermines the trust in clinical research;
- is deeply unethical.
It is high time to stop such redundant, foolish, wasteful and unethical pseudo-science.
On this blog, I have repeatedly discussed chiropractic research that, on closer examination, turns out to be some deplorable caricature of science. Today, I have another example of what I would call pseudo-research.
This RCT compared short-term treatment (12 weeks) versus long-term management (36 weeks) of back and neck related disability in older adults using spinal manipulative therapy (SMT) combined with supervised rehabilitative exercises (SRE).
Eligible participants were aged 65 and older with back and neck disability for more than 12 weeks. Co-primary outcomes were changes in Oswestry and Neck Disability Index after 36 weeks. An intention to treat approach used linear mixed-model analysis to detect between group differences. Secondary analyses included other self-reported outcomes, adverse events and objective functional measures.
A total of 182 participants were randomized. The short-term and long-term groups demonstrated significant improvements in back and neck disability after 36 weeks, with no difference between groups. The long-term management group experienced greater improvement in neck pain at week 36, self-efficacy at week 36 and 52, functional ability and balance.
The authors concluded that for older adults with chronic back and neck disability, extending management with SMT and SRE from 12 to 36 weeks did not result in any additional important reduction in disability.
What renders this paper particularly fascinating is the fact that its authors include some of the foremost researchers in (and most prominent proponents of) chiropractic today. I therefore find it interesting to critically consider the hypothesis on which this seemingly rigorous study is based.
As far as I can see, it essentially is this:
36 weeks of chiropractic therapy plus exercise leads to better results than 12 weeks of the same treatment.
I find this a most remarkable hypothesis.
Imagine any other form of treatment that is, like SMT, not solidly based on evidence of efficacy. Let’s use a new drug as an example, more precisely a drug for which there is no solid evidence for efficacy or safety. Now let’s assume that the company marketing this drug publishes a trial based on the hypothesis that:
36 weeks of therapy with the new drug plus exercise leads to better results than 12 weeks of the same treatment.
Now let’s assume the authors affiliated with the drug manufacturer concluded from their findings that for patients with chronic back and neck disability, extending drug therapy plus exercise from 12 to 36 weeks did not result in any additional important reduction in disability.
WHAT DO YOU THINK SUCH A TRIAL CAN TELL US?
My answer is ‘next to nothing’.
I think, it merely tells us that
- daft hypotheses lead to daft research,
- even ‘top’ chiropractors have problems with critical thinking,
- SMT might not be the solution to neck and back related disability.
I REST MY CASE.
The researcher who proves that highly diluted homeopathics work beyond placebo might be in for a Nobel Prize. The scientist who finds a cure for addictions probably also deserves one. The investigator who does both might get two Nobels. The question is, do these Brazilian homeopaths fulfil these criteria?
Their study investigated the effectiveness and tolerability of homeopathic Q-potencies of opium and E. coca in the integrative treatment of cocaine craving in a community-based psychosocial rehabilitation setting. A randomized, double-blind, placebo-controlled, parallel-group, eight-week pilot trial was performed at the Psychosocial Attention Center for Alcohol and Other Drugs (CAPS-AD), Sao Carlos/SP, Brazil. Eligible subjects included CAPS-AD patients between 18 and 65 years of age, with an International Classification of Diseases-10 diagnosis of cocaine dependence. The patients were randomly assigned to two treatment groups: psychosocial rehabilitation plus homeopathic Q-potencies of opium and E. coca (homeopathy group), and psychosocial rehabilitation plus indistinguishable placebo (placebo group). The main outcome measure was the percentage of cocaine-using days. Secondary measures were the Minnesota Cocaine Craving Scale and 12-Item Short-Form Health Survey scores. Adverse events were recorded in both groups.
The study population comprised 54 patients who attended at least one post-baseline assessment, out of the 104 subjects initially enrolled. The mean percentage of cocaine-using days in the homeopathy group was 18.1% compared to 29.8% in the placebo group (P < 0.01). Analysis of the Minnesota Cocaine Craving Scale scores showed no between-group differences in the intensity of cravings, but results significantly favored homeopathy over placebo in the proportion of weeks without craving episodes and the patients’ appraisal of treatment efficacy for reduction of cravings. Analysis of 12-Item Short-Form Health Survey scores found no significant differences. Few adverse events were reported: 0.57 adverse events/patient in the homeopathy group compared to 0.69 adverse events/patient in the placebo group.
The authors concluded that a psychosocial rehabilitation setting improved recruitment but was not sufficient to decrease dropout frequency among Brazilian cocaine treatment seekers. Psychosocial rehabilitation plus homeopathic Q-potencies of opium and E. coca were more effective than psychosocial rehabilitation alone in reducing cocaine cravings. Due to high dropout rate and risk of bias, further research is required to confirm our findings, with specific focus on strategies to increase patient retention.
I am glad that the authors mention the high dropout rate which clearly is a serious limitation of this fascinating trial. Had they analysed the data according to an intention to treat analysis – which, I think, would have been a better statistical approach – the results would almost certainly have been negative.
But there are other puzzling issues about this study:
- The authors say they used homeopathic remedies. I think, however, that this is not the case. Homeopathy is defined as a therapy that follows the ‘like cures like’ principle. If the remedy is based on the causative agent, as in the case of the present study, it follows a different principle (identical cures identical) and is not called homeopathy but isopathy (here an explanation from my book: “Isopathy is the use of potentised remedies which are derived from the causative agent of the disease that is being treated. It thus does not follow the supreme law of homeopathy; instead of ‘like cures like’, instead it postulates that identical cures identical. An example of isopathy is the use of potentised grass pollen to treat patients suffering from hay fever. Some of the methodologically best trials that generated a positive result were done using isopathy; they therefore did not test homeopathy and its principal assumption, the ‘like cures like’ theory. They are nevertheless regularly used by proponents of homeopathy to argue that homeopathy is effective”). This means that the above trial does, in fact, NOT test the defining principle of homeopathy.
- Moreover, I fail to understand why the authors called their trial a PILOT study. It does not explore the feasibility of a more definitive trial, but tests the effectiveness of the intervention. It is thus NOT a pilot study.
- I cannot help being suspicious of authors who, based on an extremely implausible, such as homeopathy, publish one paper after the next with positive or encouraging results.
- I am also puzzled by the fact that, in 2012 and 2013, the authors have published two previous studies along the same lines that produced encouraging results. Surely 6/5 years are a long enough period for INDEPENDENT replications to be carried out and published. And surely, a finding like this would have been replicated several times by now.
- I furthermore find it odd that the authors chose to publish their findings in the JOURNAL OF INTEGRATIVE MEDICINE. This is a 3rd class journal read only by those who promote alternative therapies. The notion that a treatment of addiction has finally be found should appear in journals like SCIENCE, NATURE, NEJM, etc.
- Considering the extremely low prior probability of their hypothesis, the authors should perhaps have not used the conventional 5% probability threshold, but one two dimensions lower.
- I have not found a statement regarding informed consent of the study participants.
So, are these Brazilian homeopaths likely to be on the next list of Nobel laureates?
I have my doubts.
What do you think?
In this RCT tested the effectiveness of foot reflexology and slow stroke back massage on the severity of fatigue in 52 patients treated with hemodialysis. Foot massage and slow stroke back massage were performed during three weeks, two sessions each week, 5 sessions in total. At the end of intervention, data of two groups were collected and compared.
The results show that the fatigue in the group receiving foot reflexology massage decreased significantly more compared to slow stroke back massage group.
The authors concluded that reflexology massage is a safe and economical nursing intervention for decreasing fatigue in hemodialysis patients.
At first glance, this might be a fairly straight forward study comparing two different interventions. One treatment yields better results than the other one, and therefore, this therapy is deemed to be the more effective one.
So far, so good.
The problem is, however, that the authors did not draw the conclusion. Instead they stated that:
- Reflexology is safe.
- Reflexology is economical.
The first point is perhaps true but cannot be concluded from the data presented. Adverse effects were not mentioned; and even if they had been noted, 52 patients is a wholly inadequate size to say anything about safety.
The second point might also be correct, but cannot be named as a conclusion, because the study was not a cost evaluation.
All of this would be hardly worth mentioning – except for the fact that such sloppy errors and illogical conclusions happen with such embarrassing regularity in the realm of alternative medicine. I feel strongly that the ‘Journal of Complementary and Integrative Medicine‘ and all similar publications must get their act together. Publishing articles such as the one discussed here only makes them the laughing stock of real scientists.
Mini-scalpel acupuncture or acupotomy is a relatively new type of non-invasive acupuncture/ micro surgery using a small needle-scalpel invented by Professor Zhu Hanzhang around 30 years ago in China. It is a slightly thicker and more blunt instrument that gets under the skin and is able to break apart adhesions and muscle knots more effectively than a regular acupuncture needle would.
Never mind, the question is does it work!
A systematic review showed that almost all studies reported an effect of acupotomy on joint pain compared to a variety of controls. On reflection, this is hardly surprising:
- all the trials were from China;
- all had major methodological flaws.
This means that we need better studies to decide the efficacy question.
This new study investigated the efficacy and safety of mini-scalpel acupuncture (MA) for knee osteoarthritis (KOA) in an assessor-blinded randomized controlled pilot trial; this would provide information for a large-scale randomized controlled trial.
Participants (n = 24) were recruited and randomly allocated to the MA group (experimental) or acupuncture group (control). The MA group received treatment once a week for 3 weeks (total of 3 treatments), while the acupuncture group received treatment two times per week for 3 weeks (total of 6 treatments). The primary outcome was pain as assessed by a visual analogue scale (VAS). The secondary outcomes (intensity of current pain, stiffness, and physical function) were assessed using the short-form McGill Pain Questionnaire (SF-MPQ) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Assessments were performed at baseline, 1, 2, and 3 during treatment and at week 5 (2 weeks after the end of treatment).
Of the 24 participants, 23 completed the study. Both groups showed significant improvements in VAS, SF-MPQ, and WOMAC. There were no significant differences between the MA and acupuncture groups. No serious adverse event occurred and blood test results were within normal limits.
The authors concluded that although both MA and acupuncture provide similar effects with regard to pain control in patients with KOA, MA may be more effective in providing pain relief because the same relief was obtained with fewer treatments. A large-scale clinical study is warranted to further clarify these findings.
I can recommend this article to anyone who wants a quick introduction into the critical analysis of clinical trials. It is a veritable treasure trove of mistakes, flaws, errors, fallacies etc. Here are just a few:
- The authors aim of investigating the safety of MA is unobtainable. It would require not 24 but probably 24 000 patients.
- The authors aim of investigating the efficacy of MA is equally unobtainable. It would require a much larger sample than 24, a sham control arm, identical treatment schedules, patient-blinding, etc.
- Calling the trial a ‘pilot’ is endearing but, except for the title and the insufficient sample size, this study has none of the characteristics of a pilot study.
- In their ‘introduction’, the authors state that miniscalpel acupuncture (MA) is a new subtype of acupuncture that is effective in treating chronic soft tissue injuries such as adhesions and contractures. This is clearly wrong but discloses their bias very plainly.
- The authors statement that both MA and acupuncture provide similar effects with regard to pain control in patients with KOA is misleading. It implies that both interventions had specific effects. Without a sham control arm, this is pure speculation.
- Similarly their assumption that MA may be more effective in providing pain relief because the same relief was obtained with fewer treatments, is pure fantasy.
- In fact, as MA requires injections of local anaesthetics, any outcome is heavily confounded by this addition.
- In the discussion section, the authors state that because MA is invasive and provides a strong stimulus, some participants complained of stiff and dull pain for few days after treatment. Yet, when reporting adverse effects in the results section, this was not mentioned.
- The way this study was designed, it should have been clear from the start that it would not produce any meaningful findings. Seen from this perspective, running the trial could even be seen as a breach of research ethics.
- According to the aims of a pilot study and the authors hope that their study would provide information for a large-scale randomized controlled trial, all reporting of outcomes is misplaced and should be replaced by information as to how a definitive trial should be conducted.
The following footnote is worth mentioning: This study is supported by a grant from the Ministry of Health & Welfare, Korea. It suggests to me that this ministry should urgently re-think its funding strategy and recruit some reviewers who are capable of critical analysis.
In my view, this is a lousy study which the authors decides to call ‘a pilot’ in order to get it published in a lousy journal.
Chiropractic is a therapy that has been in search for an indication ever since it was invented some 120 years ago. So far, this search seems to have been unsuccessful.
Perhaps it could be promoted as a means of enhancing athletic performance?
That would be excellent news for chiropractic cash-flow!
The authors of this study wanted to analyse the acute effects of spinal manipulative therapy (SMT) on performance and autonomic modulation. A total of 37 male recreational athletes who had never received SMT were assigned to a sham (n = 19) or actual SMT group (n = 18). Study endpoints included autonomic modulation (heart rate variability), handgrip strength, jumping ability and cycling performance (8-minute time trial [TT]). Differences in custom effects between interventions were determined using magnitude-based inferences.
A significant and very likely lower value of a marker of sympathetic modulation, the stress score, was observed in response to actual compared to sham SMT (p = 0.007; effect size [ES] = -0.97). A trend towards a significant and likely lower sympathetic:parasympathetic ratio (p = 0.055; ES = -0.96) and a likely higher natural logarithm of the root-mean-square differences of successive heartbeat intervals ([LnRMSSD], p = 0.12; ES = 0.36) was also found with actual SMT. Moreover, a significantly lower mean power output was observed during the TT with actual compared with sham SMT (p = 0.035; ES = -0.28). Non-significant (p > 0.05) and unclear or likely trivial differences (ES < 0.2) were found for the rest of endpoints, including handgrip strength, heart rate during the TT, and jump loss thereafter.
A single pre-exercise SMT session induced an acute shift towards parasympathetic dominance and slightly impaired performance in recreational healthy athletes.
The search was unsuccessful yet again!
SMT impaired performance; this might not convince athletes to become fans of chiropractic.
What indication should the desperate chiros try next?
One theory as to how acupuncture works is that it increases endorphin levels in the brain. These ‘feel-good’ chemicals could theoretically be helpful for weaning alcohol-dependent people off alcohol. So, for once, we might have a (semi-) plausible mechanism as to how acupuncture could be clinically effective. But a ‘beautiful hypothesis’ does not necessarily mean acupuncture works for alcohol dependence. To answer this question, we need clinical trials or systematic reviews of clinical trials.
A new systematic review assessed the effects and safety of acupuncture for alcohol withdrawal syndrome (AWS). All RCTs of drug plus acupuncture or acupuncture alone for the treatment of AWS were included. Eleven RCTs with a total of 875 participants were included. In the acute phase, two trials reported no difference between drug plus acupuncture and drug plus sham acupuncture in the reduction of craving for alcohol; however, two positive trials reported that drug plus acupuncture was superior to drug alone in the alleviation of psychological symptoms. In the protracted phase, one trial reported acupuncture was superior to sham acupuncture in reducing the craving for alcohol, one trial reported no difference between acupuncture and drug (disulfiram), and one trial reported acupuncture was superior to sham acupuncture for the alleviation of psychological symptoms. Adverse effects were tolerable and not severe.
The authors concluded that there was no significant difference between acupuncture (plus drug) and sham acupuncture (plus drug) with respect to the primary outcome measure of craving for alcohol among participants with AWS, and no difference in completion rates (pooled results). There was limited evidence from individual trials that acupuncture may reduce alcohol craving in the protracted phase and help alleviate psychological symptoms; however, given concerns about the quantity and quality of included studies, further large-scale and well-conducted RCTs are needed.
There is little to add here. Perhaps just two short points:
1. The quality of the trials was poor; only one study of the 11 trials was of acceptable rigor. Here is its abstract:
We report clinical data on the efficacy of acupuncture for alcohol dependence. 503 patients whose primary substance of abuse was alcohol participated in this randomized, single blind, placebo controlled trial. Patients were assigned to either specific acupuncture, nonspecific acupuncture, symptom based acupuncture or convention treatment alone. Alcohol use was assessed, along with depression, anxiety, functional status, and preference for therapy. This article will focus on results pertaining to alcohol use. Significant improvement was shown on nearly all measures. There were few differences associated with treatment assignment and there were no treatment differences on alcohol use measures, although 49% of subjects reported acupuncture reduced their desire for alcohol. The placebo and preference for treatment measures did not materially effect the results. Generally, acupuncture was not found to make a significant contribution over and above that achieved by conventional treatment alone in reduction of alcohol use.
To me, this does not sound all that encouraging.
2. Of the 11 RCTs, 8 failed to report on adverse effects of acupuncture. In my book, this means these trials were in violation with basic research ethics.
My conclusion of all this: another ugly fact kills a beautiful hypothesis.
Acupuncture research does not have a good name; if it originates from China, even less so.
And this note in ‘ACUPUNCTURE IN MEDICINE’ is not likely to change this image:
Fang J, Keller CL, Chen L, et al. Effect of acupuncture and Chinese herbal medicine on subacute stroke outcomes: a single-centre randomised controlled trial. Acupuncture in Medicine Published online first 10 November 2017. doi: 10.1136/acupmed-2016-011167.
This article is retracted by the Editor-in-Chief on grounds of redundant publication.
The above article reports that a trial originally planned to be carried out at three hospitals was reduced to a single centre for reasons of cost. This is incorrect. The full three-centre trial was run and reported elsewhere (Scientific Reports 6, Article number: 25850 (2016) DOI: 10.1038/srep25850).
The Scientific Reports paper was accepted for publication prior to submission of the above paper to Acupuncture in Medicine. The third author takes responsibility for the mistake. All authors have agreed to this retraction.
The abstract of the paper in SCIENTIFIC REPORTS is here:
To determine whether integrative medicine rehabilitation (IMR) that combines conventional rehabilitation (CR) with acupuncture and Chinese herbal medicine has better effects for subacute stroke than CR alone, we conducted a multicenter randomized controlled trial that involved three hospitals in China. Three hundred sixty patients with subacute stroke were randomized into IMR and CR groups. The primary outcome was the Modified Barthel Index (MBI). The secondary outcomes were the National Institutes of Health Stroke Scale (NIHSS), the Fugl-Meyer Assessment (FMA), the mini-mental state examination (MMSE), the Montreal Cognitive Assessment (MoCA), Hamilton’s Depression Scale (HAMD), and the Self-Rating Depression Scale (SDS). All variables were evaluated at week 0 (baseline), week 4 (half-way of intervention), week 8 (after treatment) and week 20 (follow-up). In comparison with the CR group, the IMR group had significantly better improvements (P < 0.01 or P < 0.05) in all the primary and secondary outcomes. There were also significantly better changes from baseline in theses outcomes in the IMR group than in the CR group (P < 0.01). A low incidence of adverse events with mild symptoms was observed in the IMR group. We conclude that conventional rehabilitation combined with integrative medicine is safe and more effective for subacute stroke rehabilitation.
I find all this odd in several ways:
- The publication of the ACUPUNCTURE IN MEDICINE article does not seem to have been a ‘mistake‘ but plain scientific fraud, in my view.
- The paper in SCIENTIFIC REPORTS (SR) was published in May 2016. Therefore the reviewers and editor of AIM could and should have spotted the fraud.
- In the SR paper, the authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article. As the authors were affiliated to three different departments of acupuncture, I feel this to be debatable.
What do you think?
