ROC curves analysis show the results of serum hs-CRP prediction in different severity of ED subgroups (including ROC curve graph with 95% Confidence bounds). (A) ROC curve for differentiating ED patients. AUC was 0.58 (95% CI: 0.56–0.61), and the cutoff value, sensitivity, and specificity were 0.37 mg/L, 70.2%, and 42.2%, respectively. (B) ROC curve for differentiating mild to severe ED. AUC was 0.63 (95% CI: 0.61–0.66), and the cutoff value, sensitivity, and specificity were 1.09 mg/L, 44.4%, and 76.3%, respectively. (C) ROC curve for differentiating moderate to severe ED. AUC was 0.71 (95% CI: 0.68–0.73), and the cutoff value, sensitivity, and specificity were 1.11 mg/L, 59.1%, and 74.2%, respectively. (D) ROC curve for differentiating severe ED. AUC was 0.79 (95% CI: 0.77–0.81), and the cutoff value, sensitivity, and specificity were 2.98 mg/L, 50.0%, and 93.3%, respectively.
