Figure 2. Features of two TRPGs clusters. (A) Consensus heatmap matrix and correlations areas of two clusters (k=2). (B) PCA analysis found the difference between the two clusters. Univariate analysis showed 42 TRPGs related to the OS (C), the DSS (D), the DFI (E), and the PFI (F). OS, overall survival; DSS, disease-specific survival; DFI, disease-free interval; DFI, progression-free interval.
