Data are expressed as arithmetic mean ± standard deviation, geometric mean (5th and 95th percentile intervals) or % of n.
†p-values between uninfected/infected and uninfected/nadir CD4 cell count were obtained with independent t-test.
‡p-values trend was obtained with ANOVA, and for gender, tobacco and alcohol users, Chi-square test was used.
