PHQ-9 = 9-item Physicians’ Health Questionnaire; SRH = self-rated health.
↵a Adjusted for PHQ-9 major depressive syndrome at baseline.
↵b Calculated with generalized linear models using generalized estimating equations with robust standard errors to allow for correlated responses within practices and individuals.
