Mortality Risk of Minor Depression in Intervention Versus Usual Care
Figure 2 shows the association between minor depression and mortality, stratified according to intervention status and medical condition. Participants in usual care with diabetes mellitus and minor depression were at greater risk of death (HR = 2.25, 95% CI = 1.12–4.53) than those without depression. In intervention practices, participants with diabetes mellitus and minor depression were no more likely to die than those without depression (HR = 1.40, 95% CI = 0.68–2.90). In usual care and intervention practices, participants with heart disease and minor depression were more likely to die than those without depression. For other conditions, minor depression did not confer greater risk of death. When participants with different medical conditions with minor depression in the intervention condition were compared with those in usual care, no statistically significant effects were observed.
