Adding tau2 confidence intervals to subgroups

General
, , ,
1

I am currently performing supbgroup anlyses on a published review. I am doing analyses on heterogeneity, and would like to get the confidence intervals for tau2 and have them printed in my forest plot.

I can't seem, to find the code for adding this, and was wondering if it exists?

This is my code - unfortunately, it does not seem like I can attach my excel file from which the data is drawn. As such the error messages generated by reprex are not relevant if you have the file loaded.
