Fig. 3From: Age in addition to RETTS triage priority substantially improves 3-day mortality prediction in emergency department patients: a multi-center cohort study3 day mortality (3dM) prediction model ROC curves. The resulting ROC curves for each model by chief complaint category. The ROC curves represent the Univariate triage priority (TP) model (blue), the univariate age model (red) and the combined TP and age model (purple). The random classifier is represented by a diagonal black straight line. From left to right, top to bottom, the assorted ED population is on top, individual CCCs are presented in order of decreasing 3dM, and the “Others” category is presented at the bottomBack to article page
