Thank you very much. To be clear, you're suggesting a meta-analysis of the
subgroup meta-analyses, correct?
Well, in my case, I have way too many subgroups, so there will be many
pairwise comparisons. I wonder if there is a way to get the large posterior
samples from each subgroup' summary effect and subtract it from the large
posterior samples from another subgroup summary effect etc.?
Perhaps, then we can see if the HDI of the posterior of difference includes
Is this possible and/or reasonable given that my goal is to see if one
subgroup is "different" from another one or not?
