Establishment and validation of the diagnostic signature based on CRGs in TCGA cohort. (A) LASSO regression to identify signature genes in ccRCC and normal samples. (B) SVM-REF regression to identify significant CRGs in ccRCC and normal samples. (C) Venn diagram based on the intersection of the two algorithms with 5 genes. (D) The IHC-P images of 5 CRGs in HPA database. (E) ROC curves of 5 signature genes for predicting diagnostic value in TCGA cohort.
