Adjusted proportion of newly-diagnosed HIV-infected patients in Durban, South Africa who underwent CD4 count by depressive symptoms and HIV testing referral pattern. Mental Health Index-5 (MHI-5) differentiates participants with depressive symptoms and no depressive symptoms. Depressive symptoms were defined as an MHI-5 score ≤60. ‘Self-referred’ subjects were those who self-referred for HIV testing. ‘Provider referred’ subjects were those who were referred for HIV testing by a healthcare provider. Generalized linear models with a Poisson distribution and log link function were used for the adjusted proportions. Proportions were adjusted for age, sex, clinic site, distance from clinic, having an HIV-infected family member or friend, history of TB treatment, functional activity score, and the interaction term HIV testing referral pattern and depressive symptoms
