- how: Any similarity however may be misleading since Ferrando and Selai determined effect sizes using between-group prepost change-scores and a fixed-effects model while the authors analyzed end-of-trial between-group effect sizes using a random effects approach and on a 50% larger sample of randomized controlled trials (RCT).
