Regarding laboratory parameters, NAFLD patients in the normal BMI group had significantly higher levels of alanine aminotransferase (26.2 U/L [12.1–93.7] vs 15.8 U/L [4.9–58.4], p = 0.000), aspartate aminotransferase (25.7 U/L [11.5–58.5] vs 22.6 U/L [12.6–69.0], p = 0.009), total bilirubin (12.6 μmol/L [6.9–30.1] vs 9.7 μmol/L [4.0–26.1], p = 0.010), C reactive protein (20.8 mg/L [1.0–94.9] vs 11.1 mg/L [0.1–101.9], p = 0.012) and triglyceride (1.4 mg/dL [0.9–6.1] vs 0.9 mg/dL [0.1–2.7], p = 0.000). This evidence concerns the gene CRP and metabolic dysfunction-associated steatotic liver disease.
