Cutoff scores of miR-let-7b and miR-let-7c and analysis of DFS in mucosal melanoma patients. Cutoff scores for miR-let-7b (a) and miR-let-7c (b) expression were 0.02452642 and 0.13255146, respectively. The AUC values for miR-let-7b (a) and miR-let-7c (b) expression were 0.634 and 0.647. c The median DFS stratified by expression of miR-let-7b versus miR-let-7c was 7.60 months versus 14.23 months (P = 0.035)
