Hepatic encephalopathy (HE) is a serious complication of cirrhosis. Clinical trials have consistently shown that L-ornithine-L-aspartate significantly improves HE symptoms. Health-related quality of life (HR-QOL) is impaired in HE patients and represents an important outcome measure for therapeutic intervention. The
