Controlled attenuation parameter for non-invasive assessment of hepatic steatosis: does etiology affect performance?

Background: Hepatic steatosis is an important parameter to assess in chronic liver disease patients. The controlled attenuation parameter (CAP) assesses liver steatosis using transient elastography.

Aim: To determine the accuracy of CAP for evaluation of hepatic steatosis in chronic hepatitis B virus (CHBV)-infected, chronic hepatitis C virus (CHCV)-infected, and non-alcoholic fatty liver disease (NAFLD) patients and to determine the influence of etiology on the diagnostic accuracy of CAP.
