Is assessing the degree of hepatic steatosis and fibrosis based on index calculations the best choice for epidemiological studies?

The use of the hepatic steatosis index (HIS) and the US fatty liver index (USFLI) to diagnose nonalcoholic fatty liver disease (NAFLD) affects the true prevalence of NAFLD. Data on controlled attenuation parameters generated by transient elastography (TE) allow for a more accurate assessment of the degree of hepatic steatosis.
