Figure 9. Tumor mutation burden (TMB) and drug sensitivity analysis. (A) The correlation of MPPS and TMB in TCGA-LUAD samples. (B) The differences of TMB between the high- and low-risk groups. (C) The Kaplan–Meier curves show OS differences stratified by TMB and MPPS. Visualization of the top 20 gene mutations in high-risk group (D) and low-risk group (E). (F) The sensitivity of 117 drugs between the high- and low-risk groups. P < 0.05 was considered as statistical significance.
