Consensus clustering analysis of FRGs expression profiles of the ccRCC patients in the TCGA dataset. A The consensus maps show the consensus clustering matrix for FRGs in the ccRCC dataset for k = 2, 3. The optimal clustering is represented by k = 2. B Consensus clustering cumulative distribution function (CDF) for k = 2 to 9. C The tracking plot for k = 2 to 9. D Principal component analysis demonstrates the gene expression differences between two clusters (cluster1 and cluster 2). E The OS in cluster 2 is significantly shorter than that in cluster 1. F Heatmap shows the clinical features between the two ccRCC patient clusters. *P < 0.05; **P < 0.01; ***P < 0.001
