I am conducting a meta-analysis and am trying to produce a forest plot displaying the mean weighted effect size with and without the outlier. I looked on so many websites and tried a lot of syntaxes, however, didn't really find anything about what I am looking for.

Assuming, there are 10 studies in the meta-analysis. Outlier-analyses showed that Study 3 is an outlier leading to an overestimation of the mean weighted ES. Accordingly, I calculate a mean ES with (k=10) and without the outlier (k=9). I would like to display the studies sorted according to their ES and report both Mean ESs in the forest plot.

Study3 Study9 Study5 ... Study7

Mean ES (k=10) Mean ES (k=9)

I would appreciate any help and/or advises.
