Longitudinal follow-up of HIV-1 plasma RNA levels and CD4+ T cell levels in eight chronically HIV-1-infected individuals undergoing STI. Time of follow-up was in weeks after initiation of first treatment interruption. HIV-1 plasma RNA, and CD4+ T cell counts are presented along the left and right y axes, respectively. If measurements were available, tabs on the left and right y axes represent pre-HAART baseline for HIV-1 plasma RNA level and CD4+ T cell count, respectively. Gray rectangles, STI periods; White rectangles, on HAART periods.
