Abstract The article focuses on estimating effects in nonrandomized studies with two outcome measurement occasions and one predictor variable. Given such a design, the analysis approach can be to include at previous time point as regression model (ANCOVA), or predict change-score of variable (CHANGE). Researchers demonstrated that both approaches result different conclusions regarding reported ...
