  1. n, number; HAART, highly active antiretroviral therapy.
  2. a different values due to missing data.
  3. b Continuous data presented by mean ± standard deviation (SD) and by median with interquartile range (IQR).
  4. c Chi-square test or Fisher's exact test were used for comparison of categorical variables between the two groups, as more appropriate. For continuous variables, "Student's" T test was used for comparison of normal distributions between the two groups. For non-normal distributions, it was used the Mann-Whitney test.
