Figure 1.
Frequency and magnitude of viral blips by Fiebig stage. A total of 69 blips ≥20 copies/mL were observed among 55 participants. The rate of blips stratified by Fiebig stage with 95% confidence intervals is presented in panel A. The magnitude of each individual blip is indicated in panel B alongside percentages observed in various magnitude categories of interest. The study population included participants who initiated antiretroviral therapy during the following Fiebig stages: Fiebig I, 46 (14.1%); Fiebig II, 79 (24.2%); Fiebig III, 131 (40.2%); Fiebig IV, 44 (13.5%); and Fiebig V, 26 (8.0%).
