Review of randomized trials of homoeopathy.

The present review covers forty published randomized trials in which the results of a homoeopathic treatment were compared to those of a standard treatment, a placebo, or no treatment at all. These trials were identified after an extensive search through the literature. They cover a wide range of pathologies. Most were double-blind and used subjective and/or multiple endpoints. The median number of patients per group was 28. The analysis only included all the randomized patients in one third of the trials. In our opinion, the results do not provide acceptable evidence that homoeopathic treatments are effective.
