Fig. 6. Area under curve (AUCs) of receiver operating characteristic (ROC) for serum miRNAs levels. The three miRNAs including miR-21 (A), miR-155 (D), and miR-365 (E) show higher sensitivity and specificity than miR-125b (B) and miR-145 (C). The AUC area, standard (Std.) error, 95% confidence interval (CI), and the P-values are indicated in the images.
