🥁 Reweighting a trial for #ExternalValidity, the target average treatment is best estimated with covariates = treatment effect modifiers (shifted or not)

Covariates that are shifted between the 2 samples but not treatment effect modifiers increase the variance while non-shifted but treatment effect modifiers do not
