  • PHQ- = 9-item Patient Health Questionnaire; SRH = self-rated health.

  • Note: Using 50 imputed data sets.

  • 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.
