GPT and metabolic dysfunction-associated steatotic liver disease: We hypothesise that analysis of the relationship between serum FFA levels and parameters of metabolic syndrome (body mass index, BMI; systolic blood pressure, SBP; triglyceride, TG; total cholesterol, TC; fasting plasma glucose, FPG), inflammatory indexes (sialic acid, SA; high-sensitivity C-reactive protein, hsCRP; white blood cells, WBC) and markers of hepatocellular damage (ALT, AST and GGT) may indirectly lead to a further understanding of serum FFA levels and NAFLD.
