Figure 8. Immune infiltration analysis of PRAN-High and PRAN-Low groups TCGA-Advanced NSCLC dataset. (A) Violin plot showing the immune cell enrichment scores of PRAN-High and PRAN-Low groups, assessed using MCPcounter. (B) The ssGSEA algorithm shows the immune cell infiltration of immune-related functions and pathways in PRAN-High and PRAN-Low groups. (C) Immune cell infiltration content of PRAN-High and PRAN-Low groups was analyzed using the CIBERSORT algorithm. The analysis provides insights into the proportion of different immune cell types in each risk group. (D) Expression of immunoinhibitor genes between PRAN-High and PRAN-Low groups. P-value: * < 0.05; ** < 0.01; *** < 0.001; **** < 0.0001.
