[Retracted] Characterization of Tumor Mutation Burden-Based Gene Signature and Molecular Subtypes to Assist Precision Treatment in Gastric Cancer

Figure 8

Association between TMB-related risk score and immune microenvironment of gastric cancer. (a) Distributions of stromal/immune scores and tumor purity in high- and low-risk groups. (b) Expression levels of immune checkpoints in two groups. (c) Infiltration levels of immune cells in two groups. (d) IC50 values to sorafenib, gefitinib, vinorelbine, and gemcitabine in two groups. values were determined by Wilcoxon rank-sum tests. Ns: not significant; value < 0.05; value < 0.01; value < 0.001.
