Table 2 Overall accuracy and ROC analyses of fibrinogen to determine DFU risk and severity

From: A potent weighted risk model for evaluating the occurrence and severity of diabetic foot ulcers

Model Cut-off AUC Sensitivity Specificity ACC
DFU risk 3.88 0.86 [0.84, 0.88] 0.74 [0.70, 0.79] 0.87 [0.82, 0.90] 0.81 [0.79, 0.83]
DFU severity 4.74 0.73 [0.70, 0.77] 0.76 [0.48, 0.88] 0.58 [0.46, 0.84] 0.66 [0.64, 0.70]
