Table 4. Multivariate analysis of factors associated with overall survival for the entire cohort LT patients.

Factor	Hazard ratio	95% CI	p-Value
Microscopic vascular invasion(Yes vs. No)	2.82	1.42–5.62	0.003
Differentiation (poor vs.moderate and well)	6.54	3.42–12.50	<0.001
Satellitosis (Yes vs. No)	1.93	1.03–3.61	0.04

P value was obtained by forward stepwise Cox regression model. Initially, 6 clinicopathologic variables (tumor number, tumor size, microscopic vascular invasion, differentiation, satellitosis, Milan criteria) were included in this model, and finally three factors remained as a significant variable.
