When an article is published in a medical journal, the authors must disclose any conflicts of interest. This is important, because even if they think owning stock in the drug company won’t influence their scientific judgment, we know that subtle biases can creep in to somehow affect the findings of studies. It has been shown that studies funded by drug companies are more likely to get positive results for their drug than studies funded by independent sources. Andrew Wakefield, author of the infamous retracted Lancet study suggesting a relationship between MMR vaccine and autism, was severely chastised for not disclosing that he received money from autism litigators and expected to earn a fortune from his own patented products if the MMR vaccine could be discredited.
I was recently contacted by an acupuncturist who plans to critique an article I wrote. It was a commentary in the journal Pain that accompanied a systematic review of systematic reviews of acupuncture by Ernst et al. For details of Ernst’s and my articles, see my previous post. He challenged my statement that I had no conflicts of interest to report. He apparently thinks I should have said I have a conflict of interest in that I am anti-CAM and anti-acupuncture. When he writes about my article, he plans to attack me for not declaring this alleged conflict of interest and he plans to set a good example with a conflict of interest statement of his own, divulging that he makes his living practicing acupuncture, has financial investments in it and many personal relationships, that his self-identity and prestige are dependent on his belief in acupuncture’s efficacy, and that he is biased towards constructivism and away from positivism. (I think this is a fancy way of saying he favors experience over the scientific method.) I agree that he has conflicts of interest, but was I wrong to say I had no conflicts of interest? I don’t think so. (more…)
