IPD reviews can be associated with higher-quality statistical analysis and may differ from aggregate data reviews. Unlike individual trials that lack power, and aggregate data meta-analysis results which suffer from confounding and aggregation bias, the use of IPD allows us to explore intervention-by-covariate interactions. However, a key limitation of conducting an IPD-MA is retrieval of IPD from original RCTs. Time and resources should be carefully planned before embarking to retrieving IPD.
