  1. *Logistic regression, n = 1,307. Some patients (n = 179) were not considered in this analysis because they had missing values in any of the variables included in the model: Education level = 7; Employment status = 25; Alcohol use = 7; Intravenous drug use = 2; BMI = 115; CD4 count = 33; HIV viral load = 27; Platelets count = 9.
  2. BMI, body mass index; ART, antiretroviral treatment; OR, odds ratio; CI, confidence interval.
