Figure 6. An immunogen-related risk score model (IRRS) was established according to sIFRGs. Heatmap of expression profiles of contained sIFRGs (A). The red parts represent upregulation, the green parts represent downregulation, and the black parts represent no difference. FDR < 0.05, log2 | FC | >1 and P < 0.05. Distribution of groups and risk score rank (B). Survival status between the low-risk group and the high-risk group (C).
