In the multivariate regression analysis, the depression care model was not significantly associated with treatment uptake (beta = .084, p = .589); the only significant correlate was severe depression symptoms (PHQ-9 score of 15–27; beta = .188, p = .002), while higher CD4 count (beta = .0002, p = .056) and better physical health functioning (beta = .002; p = .066) were marginally related to treatment uptake (see Table 2). The gene discussed is CD4; the disease is depressive symptom measurement.
