hepatic steatosis
LIVER, PATHOLOGY, LIVER FIBROSIS, HEPATIC STEATOSIS
The Pan European Observational Study has been published previously.Investigators were asked to retrieve all available hepatic ultrasound and elastography performed on the dates closest to the baseline and last follow‐up visit. The degree of hepatic steatosis was classified as mild, moderate or severe according to the criteria of local examiners. Liver elastography was measured and reported as velocity of transmission of a shear wave through the liver in kPa. Normal elastography results are in the range of 2–7 kPa.Laboratory tests were conducted according to each patient's individual visit schedule. Serum or plasma samples were analysed using local chemical pathology laboratory protocols. Among the laboratory parameters collected, hepatic biomarkers were analysed, including Fibrosis‐4 (FIB‐4). The FIB‐4 score is a simple, non‐invasive biomarker for liver fibrosis.Regardless of study, all patients provided an informed consent. All studies were conducted according to the principles of the Declaration of Helsinki.
