Figure 2. Differences in risk scores and differences in survival in subgroups with different clinical characteristics. (A) In subgroups with different clinical characteristics (T stage, N stage, M stage, tumour grade and tumour stage), the higher the malignancy of the disease, the higher the risk score. (B) The prognosis of patients in the high-risk group in the subgroups with different clinical features was significantly worse than that in the low-risk group, except for the N1 subgroup (***p < 0.001).
