ROC analysis was also performed to determine the prognostic value of URB2 expression in gliomas, in which the AUC of URB2 expression was 0.856 (1-year; Figure 5B), 0.885 (3-year; Figure 5C), and 0.881 (5-year; Figure 5D), and the C-index was 0.8009. The gene discussed is URB2; the disease is central nervous system cancer.
