| Tumor staging (III–IV) | NA | 1.12 (0.76, 1.66) | 0.576 | ||
| Vascular invasion (yes) | 2.55 (1.34, 4.86) | 0.004 | 1.89 (1.25, 2.84) | 0.002 | |
| ASA (III–IV) | 1.75 (1.04, 2.56) | 0.039 | 1.34 (1.04, 1.69) | 0.045 | |
OS, overall survival; DFS, disease-free survival; AFP, alpha-fetoprotein; ASA, American Society of Anesthesiologists; NA, not applicable. P≤0.05 was considered statistically significant.
