Standard deviations are in parentheses for T1 and unadjusted T2 scores.

^*Significance levels are P values from ANCOVA results on adjusted 6-month values (adjusted for age and number of comorbid conditions, and baseline values on the dependent variable) and accounting for clustering within physicians.

^†Lower scores indicate better quality of life.

^‡Tests for significance were run on continuous PHQ scores.
