In the last four decades,the importance of non-alcoholic fatty liver disease(NAFLD)has increased as the etiology of cirrhosis in the world and associated hepatocellular cancer(HCC).Recently,the terminology has been changed to metabolic-dysfunction associated steatotic liver disease(MASLD)(1).Importantly,a recent validation of the criteria revealed that 99.5%of NAFLD patients in a large cohort of Sweden met the MASLD criteria(2).The authors concluded that previous natural history data can be used.
