Figure 8. Risk score is an independent prognostic factor. (A) Univariate Cox regression analyses showed the clinical features such as the risk score, age, MGMT promoter status, WHO grade and IDH status were significantly correlated with prognosis. (B) Multivariate Cox analysis showed the risk score remained associated with the prognosis. (C) Nomogram was used to predict prognosis in patients at 1-, 3-, and 5-years in the CGGA dataset. (D) Calibration curve for the nomogram predicting 1-, 3-, and 5-years overall survival.
