The risks and rewards of covariate adjustment in randomized trials: an assessment of 12 outcomes from 8 studies

BACKGROUND: Adjustment for prognostic covariates can lead to increased power in the analysis of randomized trials. However, adjusted analyses are not often performed in practice. METHODS: We used simulation to examine the impact of covariate adjustment on 12 outcomes from 8 studies across a range of...
