Comparison of receiver operating characteristic (ROC) curves for the biomarker-based model and Acute Physiology and Chronic Health Evaluation (APACHE) II. The ROC curves are calculated based on the respective mortality probabilities and 28-day all-cause mortality and are based on all subjects in the combined derivation and test cohorts (n = 672). The ROC curve for the biomarker-based model (solid line) yielded an area under the curve (AUC) of 0.784 (0.747–0.820), whereas the ROC curve for APACHE II (dashed line) yielded an AUC of 0.676 (0.632–0.721).
