Fig. 2From: Validation and modification of existing mortality prediction models for lower gastrointestinal bleeding: a retrospective studyComparison of the area under the receiver operating characteristics curve (AUROC) between CNUH-4 and CNUH-5. The AUROC of CNUH-4 (left) was 0.890 (p < 0.001; cutoff, 2.5; 95% CI, 0.0851–0.929). The AUROC of CNUH-5 (right) was 0.901 (p = 0.000; cutoff, 3.5; 95% CI, 0.869–0.933). x = 1 − sensitivity, y = sensitivityBack to article page
