Both the Canadian Syncope Risk Score and FAINT score identified emergency department patients at low risk for serious outcomes, with FAINT showing higher sensitivity than physicians for serious cardiac outcomes. ja.ma/499syAD
The image shows ROC curves and calibration plots. A and B are ROC curves for \"FAINT@1\"/\"SCO@2\" and \"CSRS@3\"/\"SAO@4\" with AUROC and PER values. C and D show calibration plots for \"FAINT@1\" and \"CSRS@3\" scores, plotting observed vs. estimated risk.
