Yes, I mean a standardized mean difference or a difference between 
proportions. In many studies, participants' results are based on a 
different number of trials.


Subject: [R-meta] N of trials or participants?

When and how is it possible to use N of trials instead of N of

It is likely that this question already had a response. In this case,

please send me links or references.
