Yes, I mean a standardized mean difference or a difference between

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

participants in the standardized effect sizes estimation?

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

please send me links or references.

Thanks
