Figure 2.
Overall performance of the models. (A) Receiver operating characteristics curves and (B) precision-recall curves. Solid lines and shades indicate the mean curves and 95% confidence interval areas, respectively. SAPS II is the baseline model, and its confidence intervals are represented with a polka dot pattern. An asterisk (*) indicates a significantly higher area under the receiver operating characteristics curve than the baseline model (P < 0.05, Benjamini–Hochberg corrected).
