Figure 8. Analysis of tumor immune microenvironment. Violin plots of differences in immune scores (A), stromal scores (B), ESTIMATE scores (C), and tumor purity (D) for different risk subgroups; Bubble plots of correlations between immune cells and risk scores under six algorithms (E); Proportions of 22 immune cells in two subgroups under the CIBERSORT algorithm (F); single sample gene set enrichment analysis (G). *p < 0.05, **p < 0.01, ***p < 0.001.
