Survival and ROC curve analysis for DEGs. A Survival curve. Patients were divided into a high-risk group (> 1.009) and a low-risk group (< 1.009) according to the risk score. The difference in the survival rate between the high-risk and low-risk groups was significant (P < 0.001). B ROC curve. The calculated AUC was 0.726. The larger the AUC value, the more likely the current classification algorithm placed the positive sample in front of the negative sample
