[R-meta] extracting effect sizes from multiple regression

[Catia Oliveira]

Dear all,

I hope this email finds you well.

Is it possible to compare the findings from multiple regressions in a
meta-analysis or should one only include the effect sizes from simple
regression?  If one can incorporate those from multiple regression, should
we only compare those with effect sizes from studies that have used the
same predictors, or is there some way to extract the necessary information
from a multiple regression?
Thank you!

Best wishes
