*Cox proportional hazards regression.
^n = 1,333. Excluded patients (n = 153) had missing values in any of the variables included in the model: BMI = 115; CD4 count = 33; HIV viral load = 27.
BMI, body mass index; ART, antiretroviral treatment; Hb, hemoglobin level; HR, hazard ratio; CI, confidence interval.
