As expected, multivariate analysis based on Cox proportional hazards model showed that high FGL2 expression was an independent predictor of both OS and RFS (OS: HR, 3.396; 95% CI, 1.187–9.722; P = 0.023; RFS: HR, 2.940; 95% CI, 1.402–6.166; P = 0.004), like tumour size (P < 0.001), TNM staging (P = 0.001), Fuhrman grade (P < 0.001), and necrosis (P = 0.003). Here, FGL2 is linked to neoplasm.
