*
Adjusted for clinician race concordance with patient and clinic location, in analysis using mixed effects models with all available data.
†
Reference group is mean score at baseline.
‡
Odds ratio of depression remission, as determined by being CIDI negative at 12 months, using logistic regression analysis adjusted for clinician race concordance with patient and clinic location.
