Accuracy of the 3-miRNA classifier, clinical prognostic factors, and single miRNAs from the classifier assessed by time-dependent ROC curves of PFS. (A) Comparisons of the prognostic accuracy of the 3-miRNA classifier and existing clinical prognostic factors: sex, age, T1b or T2b, clinical stage, and CLIPi. (B) Comparisons of the prognostic accuracy of the 3-miRNA–based classifier and the single miRNAs: miR-106b-5p, miR-148a-3p, and miR-338-3p.
