Subject: [R-meta] Multi-level meta: including a measure of precision in subgroup analysis model

Hello all,

I am carrying out a multi-level meta-analysis and I have a question regarding publication bias in the context of subgroup analysis.


I have noticed that many meta-regression models include a precision measure (SE or SE^2) in their final model along with covariates. Is the same true for subgroup analysis in a multi-level analysis wherein moderators are tested individually?


For example:

moderertorX <- rma.mv(yi, vi, mods = ~ SE + moderertorX, random = list(~ 1 | EffectSize_ID, ~1 | Study_ID), tdist=TRUE, data=data)


Thanks!

Daniel
