Figure 8. Gene set variation analysis (GSVA) and correlation coefficient analysis between immune-related metagenes and the risk score in two LUAD cohorts. (A, B) Heatmaps of the enrichment levels of immune-related metagenes, including IgG, Interferon, HCK, LCK, MHC-I, MHC-II, and STAT1, in the high or low risk group in the LUAD cohorts: TCGA (A) and GSE72094 (B). (C, D) Correlograms of the risk score and seven immune-related metagenes in the LUAD cohorts: TCGA (C) and GSE72094 (D).
