  1. BMI, body mass index; Hb, hemoglobin; ALT, alanine transarninase (normal value, 0–40 U/L); AST, aspartate aminotransferase (normal value, 0–40 U/L).
  2. There were no significant differences about the characteristics between the two groups.
  3. Quantitative data are expressed as mean ± standard deviation. Numerical data were compared by t test and nominal data by Pearson χ2 test or Fisher’s exact test between groups.
