meta_regression

Mixed-effects meta-regression of effect size on a numeric moderator (REML), RENDERING a bubble plot with the fitted line. cap truncates the moderator (cap=3 replicates the published Raudenbush model min(weeks,3)); it must be > 0 and is only accepted for moderator "weeks" — capping any other field is rejected rather than silently fitted. Returns slope, p, and R^2 (a boundary-clipped proportional reduction in estimated tau^2, with no uncertainty interval).
