I was wondering whether anyone could advise on how to calculate pooled prevalence, using percentages from studies? I have found meta-analyses that have done this but cannot find any information on how to actually calculate this. Please can you advise on what the R script would look like for this? Thanks for your help.
I have searched online for advice and I would like some clarity around using percentages, as a lot of the information discusses pooled proportions and transforming this or pooled effect sizes.
