Univariate Cox proportional hazards regression analysis for overall death.

		Hazard ratio (95% CI)	P value
Age, years, mean ± standard deviation	58.9 ± 7.4	0.86 (0.08–11.81)	0.91
Gender, female, N (%)	17 (42.5)	1.73 (0.57–5.37)	0.33
Under Milan criteria, CT scan, N (%)	36 (90)	1.19 (0.23–21.79)	0.86
Under Milan criteria, explant, N (%)	22 (55)	1.43 (0.48–4.73)	0.53
Complete HCC necrosis, N (%)	19 (47.5)	0.81 (0.26–2.44)	0.71
Single HCC tumor, CT scan, N (%)	23 (57.5)	0.65 (0.21–1.95)	0.79
Single HCC tumor, explant, N (%)	12 (30)	1.29 (0.35–3.98)	0.67
Vascular invasion, explant, N (%)	9 (27.3)∗	0.54 (0.08–2.1)	0.40
Nuclear grade, undifferentiated, N (%)	5 (18.5)∗	1.03 (0.15–4.4)	0.97

^∗HCCs with complete necrosis were not evaluated for vascular invasion and for nuclear grade.
