Kaplan-Meier analysis of disease-free survival (DFS) according to the expression of circulating miRNAs and their combination. DFS in patients with high or low expression of miR-21 (a), miR-23b (b), miR-190 (c), miR-200b (d), miR-200c (e) and the combination of miR-21 and miR-200c (f). Curves were compared using the log rank test. P values are shown
