This is the story of my first incursion in to the fantasy world of alternative medicine.
I was asked by the producer of a television programme (QED) to look at a paper that claimed a beneficial effect of homeopathic treatment of fibrositis (Fisher, P., Greenwood, A., Huskisson, E. C., Turner, P., & Belon, P. (1989). Effect of homoeopathic treatment on fibrositis (primary fibromyalgia) British Medical Journal 299, 365-366.) [download pdf].
The homeopath, Peter Fisher, was kind enough to give me the raw data for re-analysis. Curiously. the two medical co-authors (apparently guest authors), neither of them homeopath, were reluctant to hand over the raw data.
It appeared from the paper that the crossover trial had been analysed incorrectly (each patient had been counted twice). When the results were analysed correctly, no significant effects were found.
Astonishingly, the British Medical Journal declined to publish the correction, but their rival, the Lancet, did so with alacrity (Colquhoun, D. (1990). Reanalysis of a clinical trial of a homoeopathic treatment of fibrositis. Lancet 336, 441-442.).[ download pdf ].
Incidentally, the result of this exercise, despite the fact that it had been commissioned by the television producer, was entirely misrepresented in the final TV programme. The producer was evidently less interested in discovering the truth, than in giving the public what he thought they wanted, i.e. wishful thinking. In this he must have been successful, because the first letter that I received after the programme was from a lady in Fulham, who asked me to recommend a source of homeopathic flu jabs for her cat.
It’s interesting, but not surprising that this correction has been universally ignored by advocates of homeopathy. Whether this is incompetence or dishonesty is impossible to say.
