<qa>  What is the primary outcome of the PHQ-9?VII. Data Analysis As the initial focus of the intervention is on the management of depressive symptoms, we have considered the PHQ-9 as a main primary outcome, and will assess changes in PHQ-9 scores over 12-months between groups, adjusting for baseline PHQ-9 score, using a mixed effects multivariate model. For our second primary outcome of improvements in global disease control, we will employ a multivariate model that jointly tests the changes in multiple clinical outcomes, namely A1c, LDL cholesterol and systolic blood pressure. Using the same analytic approach as in the recently published RCT of this intervention, we will apply a scaled marginal model Katon et al., 2010 to simultaneously compare the change in these continuous outcomes at 12 months, adjusting for the baseline status for each variable. In either primary outcome analyses, the models will be estimated iteratively and the potential correlations among and between outcomes within individuals will be handled using generalized-estimating equation GEE models for each outcome.
