We are celebrating the achievements of Cochrane’s Methods Groups from the last year. Today we are putting Individual Participant Data Meta-Analysis Methods Group in the spotlight. 

Individual Participant Data (IPD) Meta-Analysis is a specific type of systematic review. Rather than extracting summary (aggregate) data from study publications or from investigators, the original research data are sought directly from the researchers responsible for each study. These data can then be re-analysed centrally and combined, if appropriate, in meta-analyses. IPD meta-analyses are typically non-Cochrane reviews, carried out and published by collaborative groups. These groups comprise the project team managing the IPD meta-analysis, members of the advisory group (if there is one) and the researchers who contribute their study data for re-analysis.
