In the adjusted model, subjects in the fourth quartile for GGT, ALT/AST ratio, ALT, ALP, and AST had 3.29, 2.94, 2.45, 2.00, and 1.19-fold increased risk for MetS compared with subjects in the first quartile (ORs = 3.29, 95%CI = 2.70–4.02 for GGT; ORs = 2.94, 95%CI = 2.40–3.59 for ALT/AST; ORs = 2.45, 95%CI = 2.01–2.98 for ALT; ORs = 2.00, 95%CI = 1.66–2.41 for ALP; and ORs = 1.19, 95%CI = 1.00–1.43 for AST). Here, GPT is linked to metabolic syndrome.
