¹Adjusted by PET, X, Y and Z;

²By PET, X and Y;

³By maximum tumor size, X, Y, and Z;

⁴By PET, total tumor size, X and Y;

⁵By PET, X, Y, and Z;

⁶By total tumor size, X, Y, and Z. X: Microvascular invasion; Y: Major vessel invasion; Z: Intrahepatic metastasis; AUC: Area under the curves; UCSF: University of California, San Francisco; PET: Positron emission tomography; NCCK: National Cancer Center Korea; 95%CI and P value were calculated by Cox PH regression analyses adjusted by the following covariates for each criteria.
