I am conducting a meta-analysis with k = 60 studies and have to report the results for pre-post, pre-follow up and post-follow up changes in two subgroups. As I can't include 6 forest plots with 60 studies each, I would like to include something similar as the graph shown below - a summary forest-plot that only shows the total effect sizes of the different analyses, without showing the effect sizes of each study. I've already tried to find some information on how to do that, but didn't find something helpful yet. Maybe one of you can help?
I am working with metafor in Rstudio.
