[R-meta] multilevel models and bias assessment

Dear all,

I hope you are well.
Given that we should not conduct Egger's regression on effect sizes with
dependency, would it be more adequate to aggregate all effect sizes coming
from the same study or is it OK to just combine effect sizes when they come
from the same participants? I know the latter ignores the nested nature of
the data, so I just wanted to check whether it is adequate to do so just
for bias assessment.

Best wishes,

Catia
