Hi everyone. I am currently doing a meta analysis and have created a forest plot with 5 studies so far. I have also created separate forest plots for other studies which I want to now add in to the larger plot. Using the meta, metafor, esc R packages.
Does anyone know if there is a way to add the overall effects obtained in another forest plot (below) to the overall forest plot? I would also need to add the Author/study name and their corresponding effect sizes/standard errors. Any help is appreciated!
