Liver biopsy is currently considered to be the reference test for assessing the extent of fibrosis and inflammation, however it has certain limitations. Objective: To evaluate and compare the diagnostic performance of pulse elastometry (EI), FIB4, APRI and GPR to predict significant fibrosis during chronic hepatitis B in a Tunisian population.Methods: Prospective analytical study, spread over a period of 3 years from January 2015 to December 2017, carried out at the gastroenterology department of the Sahloul University Hospital Center of Sousse on patients followed for chronic hepatitis B.
