Thanks for your reply. Which function I should explore in "metafor" package for this kind of plot.
Also I have to do a forest plot for "regressions estimates" (betas) and corresponding "sqrt(var)". I hope in this case there is no difference between std. error and std. deviation? So, a 95% confidence interval would be [estimate +/- 1.96*sqrt(variance of estimate)]. Am I correct in saying this?
