3.4. TMB analysis of the risk score

TUMOR
Immunotherapy has been a promising treatment in CRC, and evidences implied that TMB was closely related to sensibility of immunotherapy. In present study, TMB was significantly higher in the low-risk group ((A) Comparison of TMB levels between high-risk group and low-risk group. (B) The correlation among TMB levels and risk score. (C) The differential expression analysis of immune checkpoint genes between high-risk group and low-risk group. TMB = tumor mutation burden.
