Fig. 2: Cumulative incidence for the risk of psychotic disorders in Commercial Database and SLaM derivation database.

Upper part of the figure: cumulative incidence (Kaplan–Meier failure function) for risk of development of psychotic disorders in the Commercial Database. There were a total of 24,941 events (transition to psychosis): 19,687 in the first 365 days, 4,851 in the interval 366–730 days, 403 in the interval 731–819 days. The last event was observed at 819 days, when 360,396 individuals were still at risk. The cumulative incidence of psychosis was: 0.94 (95% CI: 0.93–0.95) at one year and 1.43 (95% CI: 1.41–1.45) at two years. Lower part of the figure: cumulative incidence (Kaplan–Meier failure function) for risk of development of psychotic disorders in the SLaM derivation database, truncated at 1,460 days for visual comparability. Cumulative incidence of psychosis: 1.67 (95% CI: 1.61–1.89, 30,102 individuals still at risk) at one year, 2.57 (95% CI: 2.40–2.75, 26,337 individuals still at risk) at two years.
