The figure shows the number of HPTN 068 participants who were HIV-infected at study enrollment and the number of women who acquired HIV infection during study follow-up (F/U). For each group, the figure shows the number of those participants who had no antiretroviral (ARV) drugs detected at their first HIV-positive visit (enrollment or seroconversion), the number of participants with viral load levels <2,000 copies/mL at their first HIV-positive visit, the number of participants with at least 12 months of follow-up, and the number identified as viremic controllers. Loss of virologic control was defined as having two or more HIV RNA measurements >2,000 copies/mL during study follow-up.
Abbreviations: mo.: month; F/U: follow-up.
