  1. †Expressed as the mean ± standard deviation. ††Expressed as the number of subjects (%). Values in bold, statistically significant (p < 0.05).
  2. § Available data in 18 patients. Eighteen patients with cryptogenic HCC were matched for age and sex (1:2 ratio) with HBV-HCC or HCV-HCC patients.
  3. ¶ Of 55 ALC-HCC, VFA was measured in 23 patients. ALC-HCC patients did not match with regard to age and sex with cryptogenic-HCC patients because they were mostly of male gender and because the sample sizes of each subgroup were small.
  4. HU, Hounsfield unit; VFA, Visceral fat accumulation; BMI, Body mass index.
  5. *p: Cryptogenic HCC vs. HBV-HCC.
