I am the author and maintainer of the CRAN task view on meta–analysis https://CRAN.R-project.org/view=MetaAnalysis, and a package to do meta-analysis of significance values https://CRAN.R-project.org/package=metap

I have been involved in a number of conventional systematic overviews usually with meta–analysis [1098716614152] and individual patient data meta–analyses [1712]. Two collaborative re–analyses in which I was both a data provider and also part of the re–analysis effort were the EURODEM study [11113], and the EURODEP study [543]
