Nonalcoholic hepatic steatosis is present in 33% of the adult population in the United States 1 and is characterized by the accumulation of triacylglycerol (TAG)-rich macrovesicular and/or microvesicular lipid droplets within the hepatocytes, in the absence of inflammation or liver injury. To monitor these histopathological changes, several histological scoring systems, including the NAFLD activity score (NAS) and the fibrosis scoring system, were established.
