We've got two online IPD meta-analysis training courses this Autumn, with places still available - one is a general introduction about doing IPDMA projects (the whole process, not just the stats bit) & the other is about the statistical modelling aspects - more here:

Some of the more recent work by Richard Riley communicates quite well on that matter in the context of "classic meta-analysis vs. MLM" (doi.org/10.1002/jrsm...).
Two‐stage or not two‐stage? That is the question for IPD meta‐analysis projects
Individual participant data meta-analysis (IPDMA) projects obtain, check, harmonise and synthesise raw data from multiple studies. When undertaking the meta-analysis, researchers must decide between ...
