The practical utility of non-invasive indices in metabolic hepatic steatosis.

Background: Metabolic hepatic steatosis (metHS) is the most frequent cause of chronic liver disease in our environment. The "gold standard" for its diagnosis continues to be liver biopsy, but this is an invasive technique, is not risk-free, and has great interobserver variability, so noninvasive diagnostic methods are necessary.

Objective: To determine the diagnostic accuracy of non-invasive methods based on clinical and analytical data compared to liver biopsy, and to analyse their concordance with each other in the overall cohort and in subpopulations at risk of metHS.
