In population of two pre‐pubertal cohorts, German and Italian, miRNA (GC: 0.77; IC: 0.54) and serum markers – CK18 (GC: 0.78; IC: 0.54), ALT (GC: 0.89; IC: 0.70) – had the similar potential of differentiating patients with NAFLD from healthy ones (as measured with AUC). The gene discussed is GPT; the disease is metabolic dysfunction-associated steatotic liver disease.
