Re: Re: Good Intention
Thanks but, does it indicate/prove "abosolut nothing" in homeopathic remedies? Moreover, it is not homeopath's report?

Statistics in study were flawed
EDITOR - Taylor et al come to the conclusion that their study of homoeopathy versus placebo in perennial allergic rhinitis "has failed to confirm our original hypothesis that homeopathy is a placebo."1 Unfortunately, the statistics do not prove that.
The basis for the study was a prestudy power calculation that required 120 patients to prove the hypothesis with a 5% significance and an 80% power.2 In fact, the authors only recruited 51 patients but analysed the results as if they had the required number. Their only conclusion was that they did not have enough data to make a conclusion.
If we accept the availability of only 51 patients at the outset, what are the relevant calculations? The power calculation is only 43%, and to maintain the power calculation at 80% the P value becomes 34%. The only conclusion is that the trial is not able to prove anything.
