In Reply On behalf of my coauthors, I thank Dr Dubois for highlighting the error of reporting treatment effect in the article that described the results of the cluster randomized clinical trial of the Healthy Buddies Curriculum, recently published in JAMA Pediatrics.1 Dr Dubois correctly highlighted the fact that the “the use of a measure’s standard error for calculating an effect size is problematic” because it would inflate the estimate of the effect size.
