Figure 7. DFS of the signature with multiple genes in RCC. (A) Patients were classified by risk score and their survival status; (B) DFS of the signature of multiple genes in this model, which indicated that patients in the low-risk group had a better DFS than those in the high-risk group. (C) ROC curves suggested that the accuracy of this model was 74.3%, 74.7% and 77.4% at 1, 3 and 5 years, respectively.
