The analysis
The retrieved literature contains conflicting findings: older or specific subset meta-analyses report statistically significant differences favoring homeopathy over placebo, but higher-quality comprehensive reviews and trials controlling for bias or specific factors (such as the consultation process) conclude that the effects are not robustly distinguishable from placebo.
A state-of-the-art review found individualized homeopathy significantly more effective than placebo in pooled trials, while noting methodological shortcomings.
A randomized trial found that clinical benefits in rheumatoid arthritis are attributable to the consultation process rather than the homeopathic remedy itself.
