Hi, It sounds like you will want to engage in a meta-analysis.
There is a CRAN task view here: https://cran.r-project.org/web/views/MetaAnalysis.html that would be relevant in pointing you to tools in R that can support that approach. That being said, the details of specific methodologies and conceptual assistance would be beyond the scope of this list. You should consider consulting a local statistician for assistance with that, if needed.
