- Shang, A., Huwiler-Müntener, K., Nartey, L., Jüni, P., Dörig, S., Sterne, J.A., Pewsner, D., Egger, M., 2005. Are the clinical effects of homoeopathy placebo effects? Comparative study of placebo-controlled trials of homoeopathy and allopathy. The Lancet 366, 726–732.
- 110 trials with an average of 65 participants per trial.
- The paper is a systematic review / meta analysis of all relevant trials.
- This means that the data from all similar trials has been grouped to form an overall outcome.
When the analysis was restricted to large trials of higher quality, the odds of a positive effect was increased by 12% for homoeopathy (eight trials) and 42% for conventional medicine (six trials).
- No (without confidence)
- The authors conclude that the clinical effects of homoeopathy are placebo effects.
