Nomogram for predicting 5- and 8-year overall survival in patients with ccRCC. a Nomogram for predicting clinical outcomes integrated with Fuhrman grade (1/2/3 + 4), TNM stage (I + II/III + IV), tumor size (continuous variable), necrosis (absent/present), ECOG PS (0/≥1), and ST3GAL-1 expression (low/high); b Calibration plot for nomogram predicted and observed 5-year overall survival rate; c Calibration plot for nomogram predicted and observed 8-year overall survival rate. Line of dashes: ideal model, vertical bars: 95 % confident interval. ECOG PS = Eastern Cooperative Oncology Group performance status. Higher total point indicated a more adverse outcomes probability
