CDCA7 was overexpressed in ccRCC and associated with overall survival (OS). a The expression of CDCA7 in various cancers in TCGA dataset. b Relative expression levels of CDCA7 in ccRCC and normal kidney tissues in TCGA dataset (N = 72; T = 531). c Pairwise boxplot of CDCA7 expression between ccRCC and matched normal tissues in TCGA dataset (N = 72; T = 72). d External validation of relative expression levels of CDCA7 in ccRCC and normal kidney tissues in ICGC dataset (N = 45; T = 91). e CDCA7 mRNA expression in 16 pairs of ccRCC tissues and matched adjacent non-cancerous tissues. f Kaplan–Meier curve for low-risk and high-risk groups in TCGA database. g Kaplan–Meier curve for low-risk and high-risk groups in ArrayExpress database (E-MTAB-1980; T = 99). h ROC curve of CDCA7
