Figure 8. Characteristics of the immune microenvironment of the tumor. (A) Immune cell bubble of different risk cohorts. (B) Heatmap showed the relationship between MMGrisk and immune-related functions. (C) The expression levels of the immune checkpoint genes between the two risk groups. (D) Analysis of immune subtypes in the two risk cohorts. (E–G) Differences expression levels of stromal, immune, and ESTIMATE scores between the two risk cohorts.
