perform subgroup meta-analysis and create forest plot displaying subgroups
...beneath each subgroup.
I am able to generate the subgroup analyses by simply performing 3 separate meta-analyses with the desired subset of data. However, I can't manage to plot everything on the same forest plot.
My data and code appear as follows:
data(meta)
subgroup study beta se
subgroupA site1 -0.35 0.12
subgroupA site2 -0.34 0.1
subgroupB site1 -0.28 0.06
subgroupB site2 -0.29 0.07
subgroupC site1 0.34 0.03
subgroupC site2 0.36 0.04
