Significant association between ST3GAL4 expression and poor prognosis in gliomas. A–C: Kaplan-Meier curve analysis using the TCGA database was conducted to assess overall survival (A), disease-specific survival (B), and progression-free interval (C) in patients with gliomas. D–I: ST3GAL4 expression within various subgroups: WHO grade (D), 1p/19q codeletion (E), gender (F, G), and age (H, I), correlated with glioma prognosis (P < 0.005). J: Cox analysis was used to evaluate the diagnostic value of ST3GAL4 expression level in gliomas. K–M: Cox analysis to predict the relationship between ST3GAL4 and glioma prognosis, considering various clinical feature states, including WHO grade (K), IDH status (L), and time points (M). N: Calibration plot of the nomogram for OS prediction. O: Nomogram survival prediction chart for predicting the 1-, 3-, and 5-year overall survival rates.
