Values are presented as mean±standard deviation or number (Proportion, %). The dataset include missing values, however we did not consider them when we calculate statistics.

BMI, body mass index; HbA1c, glycated hemoglobin; HDL, high density lipoprotein; HBsAg, hepatitis B surface antigen; AST, aspartate aminotransferase; ALT, alanine aminotransferase.

aP-values were derived from χ2 test or Mann–Whitney U test.
