Table 2. Univariate and multivariate linear regression analyses to determine the factors related to the TVDT of untreated HCC.

Variables with alpha <0.05 in the univariate analysis were included in the multivariate analysis.

^*Beta was calculated per an increment of 1 year or 1 cm.

TVDT, tumor volume doubling time; HCC, hepatocellular carcinoma; SE, standard error; AFP, alpha fetoprotein; PIVKA-II, protein induced by vitamin K absence; HBV, hepatitis B virus; HCV, hepatitis C virus.
