  1. The median was used as cut-off of necroinflammatory grade, fibrotic stage and DR respectively. Variables with p <0.05 in univariate analysis were adopted for multivariate analysis. Tumor size and DR were included, other covariates including tumor number, tumor capsule and portal vein invasion were then excluded.
