[R-meta] Mean and SD or unstandardized regression coefficients?

[Stefanou Revesz]

Dear Meta-Analysis Experts,

My sample of longitudinal studies both provide the raw descriptive
statistics (mean, sd) for groups at different time points as well as
the unstandardized regression coefficients for group*time interactions
often adjusted for various confounding variables which may not be the
same across the studies.

To meta-analyze these studies, is it better to meta-analyze the
adjusted unstandardized regression coefficients for group*time
interactions or the raw (i.e., unadjusted) descriptive statistics
(mean, sd) for groups at different time points?

Thanks,
Stefanou
