According to the results, the mean age (p = 0.003), body mass index (BMI), waist circumference (WC), fasting plasma glucose (FPG), insulin, homeostasis model assessment of insulin resistance (HOMA-IR), aspartate aminotransferase (AST), alanine aminotransferase (ALT) (p < 0.001 for all) and gamma glutamyl transpeptidase (GGT) (p = 0.002), levels of the three groups were significantly different. Here, GGTLC1 is linked to Insulin resistance.
