I read the systematic review and meta-analysis of interventions to reduce depression, anxiety, and suicide ideation in physicians by Katherine Petrie and colleagues1 with great interest. Because the mental health of physicians has become increasingly important, this paper is timely. However, I wish to raise some minor concerns regarding some methodological aspects.
