Cumulative meta-analysis

 

In cumulative meta-analysis studies are added one at a time in a specified order (e.g. according to date of publication or quality) and the results are summarised as each new study is added. In a graph of a cumulative meta-analysis each horizontal line represents the summary of the results as each study is added, rather than the results of a single study.

A useful discussion of cumulative meta-analysis can be found in Bandolier 97.
