The overall model was highly significant (Omnibus test of model coefficients, p<0.001), confirming that the included predictors together contributed significantly to survival.

Other factors, including Child-Pugh class (HR=1.24, 95% CI 0.82 to 1.88, p=0.31), repeated surgery (HR=1.65, 95% CI 0.92 to 2.97, p=0.09), and preoperative variceal sclerotherapy (HR=0.77, 95% CI 0.55 to 1.07, p=0.12), were not independently associated with survival in the multivariate model, although some showed borderline significance.
