Figure 4. Receiver-operating characteristic (ROC) of the optimal cutoff values for preoperative serum CRP in predicting ER and LR.

Figure 4

(a) Preoperative serum CRP as indicator of ER with the area under the curve (AUC) of 0.65 (95% CI, 0.58–0.72) and the optimal cutoff point was 1.5 mg/dl with a sensitivity of 60.6% and a specificity of 69.4%. (b) Preoperative serum CRP as indicator of LR with the AUC of 0.63 (95% CI, 0.54–0.71). The optimal cutoff point was 1.5 mg/dl with a sensitivity of 56.2% and a specificity of 69.4%.
