ESS: Epworth Sleepiness Scale.

ESS (median, IQR).

Values shown are N(%) or median (25^th percentile –75^th percentile).

^aP-values are for comparison of HIV− to HIV+ participants.

^bP-values are for comparison of HIV+/HAART+ to HIV+/HAART− participants.

*P<0.05, compared to HIV−.

Comparisons of data represented by medians were performed using the Wilcoxon ranksum test for 2 group comparisons.

Comparisons of categorical data represented by percent were performed using chi-square analysis and the Fisher’s exact test.
