Figure 2. Receiver operating characteristic curve showing the discrimination of the clinical prediction model for maternal end-organ injury or death.
Legend: Outcomes are those arising between 20 weeks’ gestation and 42 days after birth using variables measured in the index pregnancy prior to 20 weeks’ gestation (2a); the index pregnancy prior to 20 weeks’ gestation and pre-pregnancy (2b); the index pregnancy prior to 20 weeks’ gestation, pre-pregnancy, and in a previous pregnancy (2c). Analysed is the cohort of 333,435 births among parous women.
Legend, panel a: C-statistic for Area Under the Curve = 0.61 (95% CI 0.59-0.63).
Legend, panel b: C-statistic for Area Under the Curve = 0.69 (95% CI 0.67-0.70).
Legend, panel c: C-statistic for Area Under the Curve = 0.71 (95% CI 0.69-0.73).
