摘要

Meta-analysis is a statistical technique for pooling clinical trials of similar design. It achieves higher statistical power for detecting differences between treatments and obtaining more precise estimates of outcome. Meta-analysis quickly chalked up some notable successes after its introduction to medicine. Meta-analysis of several small studies suggested thrombolytic treatment would reduce mortality from acute myocardial infarction by 20%, a prediction confirmed by subsequent large randomised trials. The value of the meta-analysis in providing a quantitative overview of data from many studies soon became apparent. Optimists suggested that cumulative meta-analysis of small trials would identify effective treatments sooner, and there were even hints that meta-analysis might make large randomised trials unnecessary.
