  1. ALT alanine transaminase, AST aspartate transaminase, FH family history, FPG fasting plasma glucose, FSI fasting serum insulin, GTC green tea consumption, HbA1c hemoglobin A1c, HDL-C high-density lipoprotein-cholesterol, LDL-C low-density lipoprotein-cholesterol, SD standard deviation, γ-GTP γ-glutamyl transpeptidase. The p-values shown in bold are statistically significant (p < 0.05).
  2. aContinuous variables are shown as mean with standard deviation and were analyzed by unpaired t-test. Body mass index was calculated as body weight (kg) divided by height squared (m2)
  3. bCategorical variables are shown as number of individuals (%) and were analyzed using a Χ2 test
