Diagnostic Utility of Triglyceride-Glucose Index in Non-Alcoholic Fatty Liver Disease: A Cross-Sectional Study on Lean Population

Approximately 10-20% of individuals with non-alcoholic fatty liver disease (NAFLD) are lean, and the underlying pathophysiology is not yet understood. This study aims to explore the characteristics and the diagnostic value of triglyceride-glucose index (TyG) in early diagnosis of lean NAFLD.
