The prediction performance of 6-miRNA-classifier in the clinical cohort. (A) The predictive power of 6-miRNA-classifier was demonstrated in stage II/III patients by ROC analysis. (B,C,D,E) All the patients were divided into low and high-risk group based on risk scores calculated from 6-miRNA-classifier. The Kaplan-Meier analysis was used to estimate the prognosis of low and high-risk group in stage II and stage III. *, P<0.05; **, P<0.01. HR, hazard ratio; ROC, receiver operating characteristic; AUC, area under curve; DFS, disease-free survival.
