Additional factors retained in the final Cox model based on the akaike information criteria included serum AFP level (HR = 1.7; 95% CI: 1.2, 2.5; p = 0.007), tumor multiplicity (HR = 1.6; 95% CI: 1.0, 2.5; p = 0.06), and MVI (HR = 1.8; 95% CI: 1.2, 2.7; p = 0.003) (Table 2). Here, AFP is linked to neoplasm.
