Three validated mRNAs may act as significant prognostic markers in ccRCC classification. a Kaplan–Meier analysis of overall survival in the light of patient median risk score to assess prognostic value. P values were calculated using the log-rank test. b A receiver operating characteristic (ROC) curve was analyzed by univariate and multivariate regression models based on patient risk scores. The score performance of ROC was validated by calculating the area under the ROC. c–f The mRNA expression of CRHBP between normal and ccRCC group in GSE68417, GSE36895, GSE53757, GSE66270
