Fig. 1

Survival curves with first blip magnitude either in categories (left) or as a continuous measure (right) [24]. Curves are shown for the first suppression episode (top) and for subsequent suppression episodes (bottom). All curves are for the same reference patient: a male who did not acquire HIV though injection drug use, starting a suppression episode in 2005 at the age of 40, on a non-nucleoside reverse transcriptase based regimen, with a CD4 cell count of 350 cells/μL and with HIV RNA measured using an Amplicor ultrasensitive assay
