Abstract:

Baseline covariate adjustments are often made in the analyses of randomized controlled trials. However, the results with adjustments for covariates that are measured not at baseline but after randomization could be misleading because such covariates may be affected by the treatments. Therefore, such results must be viewed with caution. Examples will be presented for illustration purposes.
