Core Tip

Core Tip: Metabolic dysfunction-associated steatotic liver disease affects both lean and non-lean individuals. This meta-analysis of over 10 million participants found that non-lean patients had greater odds of hepatic steatosis, fibrosis, cirrhosis, and hypertension. Lean patients, however, showed similar risks of nonalcoholic steatohepatitis, cardiovascular disease, and mortality. These results support expanding metabolic dysfunction-associated steatotic liver disease screening and risk assessment beyond obesity-related criteria.
