  1. Data are represented as the mean ± SD (25th, 50th, and 75th percentile). P values were obtained by comparing the quantitative phenotype between 2 groups (Mann-Whitney U test). *Men/women ratio was analyzed by Fisher's exact test. AST, aspartate transaminase; ALT, alanine transaminase; BMI, body mass index; FBS, fasting blood sugar; HbA1c, hemoglobin A1c; HDL, high-density lipoprotein; NAFLD, nonalcoholic fatty liver disease.
