Correlation of miRNA expression with clinical outcome. (A) Differential miRNA expression between patients in the highest tertile (n = 10) and lowest tertile (n = 10) of the proliferation signature (P < .05). (B) Kaplan-Meier curves of miR-636 and miR-424 showing significant (P < .05) association with OS on univariate analysis. (C) Kaplan-Meier curves for risk groups using the 6-miRNA signature obtained for survival risk prediction using the method of Bair et al.29
