aOR, adjusted odds ratio; CI, confidence interval; OR, odds ratio.

^*Statistically significant association (α = 0.05).

^aTime was modeled as a binary variable: pre-HAART visits vs. all visits post-HAART.

^bTime was modeled with only the visits 1 year prior to HAART initiation vs. visits categorized into time-periods after initiation up to more than 5 years of follow-up.

^cAdjusted for age, sex, race, alcohol usage, employment status, CD4 cell count, and year of HAART initiation (1996–1997, 1998–2000, 2001–2007).

^dUnprotected sex includes the subgroup of participants that reported any sexual behavior.

^eNeedle-sharing includes the subgroup of participants that reported any injection of drugs.
