Characteristics associated with six month mortality were gender (HR females versus males 0.54, 95%CI: 0.34–0.85), years of initiation (HR 2009 versus 2005 0.54, 95%CI: 0.41–0.80), low baseline CD4 (HR 350–500 cells/mm3 versus <50 cells/mm3 0.26, 95%CI: 0.18–0.52), low baseline BMI (one unit increase: HR 0.96, 95%CI: 0.94–0.97), co-infection with TB (HR 1.61, 95%CI: 1.46–1.95), history of injecting drugs (HR 1.58, 95%CI: 1.31–1.78). Here, CD4 is linked to tuberculosis.
