Thus, lower concentrations of hepatic enzymes ALT (Δ = −9.1 U/L) and GGT (Δ = −9.1 U/L) were shown, which in elevated concentrations are both highly related to liver and abdominal fat, and predictors of the MUO phenotype, the diagnosis of non-alcoholic fatty liver disease, type 2 diabetes, and subclinical atherosclerosis [35]. Here, GPT is linked to type 2 diabetes mellitus.
