Summary
Bringing together the evidence from randomised controlled trials is increasingly common. Depending on the techniques used, the process might be called a systematic review, meta-analysis or collaborative overview. All relevant trials are identified and those of a satisfactory standard are reviewed. In a meta-analysis, each trial is assessed separately and the summary statistics are then combined to give an overall result. Neither meta-analyses nor systematic reviews are a substitute for prospective clinical trials, rather, they are a complement to them.
