¹The value was compared by Student's t test;

²The relation with variables was evaluated by Pearson χ² test;

³The value was compared by Wilcoxon’s rank-sum test;

⁴The value of THKmax according to the cell-types and Lugano staging;

⁵The relation with variables was evaluated by continuity correction χ² test. SUVmax: Maximal standard uptake value; THKmax: The maximal thickness.
