Figure 6. Associations between the DRG score and TMB as well as ICGs. (A, B) A comparative analysis of mutational profiles in two risk groups of LUAD. (C) Correlations between TMB and the DRG score within various gene clusters. (D) Disparities in TMB score among high-risk and low-risk groups. (E) Correlations between the expression of ICGs and the five genes included in the DRG prognostic model. (F) Correlations between the expression of ICGs and the DRG score. *P < 0.05, **P < 0.01, ***P < 0.001.
