Figure 7. Correlation between immune cell infiltration level and risk score. (A) Identification of the relative infiltration of 28 types of immune cell subpopulations in the high- and low-risk signature subgroups. (B) The correlation between immune infiltration cells and the risk score. (C) The relationship between the risk score and immunotherapy-relevant pathways. (D, E) The risk score was positively correlated with MDSC levels but negatively correlated with the microsatellite instability (MSI) index. (F) Evaluation of the TIDE score between the high- and low-risk groups.
