Visual Representation of Systematic Review

#1
Hello everyone

Stats are very much my weak point so apologies if this is a bit of a basic explanation! I've conducted a systematic review and would like to represent the data visually. I believe a forest plot is used for this however I have no common value statistical analysis from the studies which I think you need for this (please correct me if I'm wrong!).

The statistical analysis reported give me outcomes in the form of differing combinations of d test, df test, f test, t test and z test.

Is it possible/usual to find a common value from this data or are there any suggestions for how to represent this visually? I have 29 studies to show.

Thank you in advance!
