Sub-HAART†
256 (33.9)
HIV: human immunodeficiency virus; RNA: ribonucleic acid. (%) = number of subjects and percent of HIV-infected or HIV-uninfected cohort.
*Percent of those who were generic probe positive. †Sub-HAART was defined as self-reported use of any antiretroviral(s) that combined do not qualify as highly active antiretroviral therapy (HAART) according to the Department of Health and Human Services guidelines [26].
