Analysis of AOI-related morbidity. a Kaplan–Meier curves of accumulated AOIs in patients with newly diagnosed HIV infection in the three study periods. The probabilities of accumulated AOI events did not significantly differ among the three study periods (log-rank test, P = 0.594). In all three periods, the probability of an AOI event increased sharply during the first 3 months following initial HIV care. b Stratification of AOIs by interval since enrollment and mortality in each enrollment period. Of the 290 AOI events in the observation period, 96 (33.1%) occurred in period 1, 111 (38.3%) in period 2, and 83 (28.6%) in period 3; 266 of the 290 events developed within 90 days of HIV enrollment (91.7%). The proportion of events that occurred within 90 days did not differ across groups after stratification by interval after the initiation of HIV care (P = 0.105). The overall mortality of each AOI event was 16.9% [14.6% in period 1, 20.7% in period 2, and 14.5% in period 3 (P = 0.817)]
