The objective was to review the current status of meta-analysis, the process of combining the results of similar investigations, which was described in 1976.
It has evolved rapidly, and thousands have already been published.
Meta-analysis may be performed in a narrative form or in the preferred statistical format, which is more rigorous and demanding.
The criteria for designing and performing a meta-analysis of high quality are presented and discussed in detail, including selection criteria, quality, biases and heterogeneity, both of component studies and of results.
Critical reviews of meta-analyses are presented.
Examples are given from my own field - hepatology - and from my own research experience.
Although meta-analysis is simple in concept, it is complex in execution.
If performed with insufficient insight or attention to detail, it may give ambiguous or erroneous results.
