GPT and metabolic syndrome: After multivariable adjustment, abnormal levels of GGT (OR = 1.91, 95% CI: 1.61-2.28, <i>p</i> < 0.001), ALT (OR = 1.60, 95% CI: 1.34-1.90, <i>p</i> < 0.001), ALP (OR = 1.48, 95% CI: 1.07-2.03, <i>p</i> = 0.01), and AST (OR = 1.39, 95% CI: 1.09-1.77, <i>p</i> = 0.007) were significantly associated with higher odds of MetS.
