A meta-analysis published in the Lancet in September 1997 cautiously concluded that homeopathic drug activity is not fully explained by the placebo effect. A thorough examination of this meta-analysis reveals design errors that make the results untrustworthy. There is still nothing to suggest that homeopathic drugs are any more effective than a placebo.
1997年9月发表在《柳叶刀》上的一项荟萃分析谨慎地得出结论,顺势疗法药物的活性不能完全用安慰剂效应来解释。对这项荟萃分析的全面审查发现了设计错误,这使得结果不可信。仍然没有任何证据表明顺势疗法药物比安慰剂更有效。
