Identification of VSX1 as a prognostic biomarker in ccRCC. a Venn-diagram analyses of candidate genes from the TCGA database. b VSX1 mRNA expression in diverse human malignancies. Statistical significance was calculated using the Wilcoxon test. c VSX1 mRNA expression was higher in ccRCC tissue than in the adjacent normal tissue in the TCGA database. The significance of the difference was evaluated using the paired Student’s t-test. d VSX1 mRNA expression was analyzed in different pathological stages for ccRCC in the TCGA database. The significance of the difference was evaluated using unpaired Student’s t-test. *P < 0.05, ** P < 0.01, and *** P < 0.001
