ROC curve of miRNA risk scores (miR-21, miR-126 and CRS) and Kaplan Meier survival analysis of cancer specific survival (CSS) in RCC patients stratified by miR-21, miR-126 and CRS expression data. A) ROC curves; the cross indicates the selected cutoff score for miR-21, miR126 or CRS resulting in highest sensitivity and specificity. The used cut-off scores were indicated in the graphs. B) Kaplan Meier curves with log rank test and numbers of patients stratified by the calculated risk scores of miR-21, miR-126 and CRS.
