Therefore, we evaluated seven indices representing diverse origins, including the widely adopted adult scores (APRI, FIB-4, NAFLD fibrosis score (NFS), AST/alanine aminotransferase (ALT) ratio (AAR), albumin platelet index (API)), the metabolism-oriented triglyceride-glucose index (TyG) and the pediatric-specific PNFI, to comprehensively evaluate and compare their diagnostic performance in Chinese children with MASLD. This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
