Figure 8. Relationship between DRG risk scoring model and immune cell, immune checkpoints, somatic mutations, TMB, and immunotherapy. (A) The association between risk scoring genes, risk score, and immune cells. (B) Differences in immune cell infiltration between high and low-risk groups. (C) TME scores for high and low-risk groups. (D) The expression of immune checkpoint genes in the high-risk and low-risk groups. (E, F) Frequency of somatic mutations in high and low-risk groups. (G) IPS results from the TCIA database for high and low-risk groups. P < 0.05 was considered statistically significant.
