Current guidelines for the diagnosis of hepatic encephalopathy (HE) include the clinical sign asterixis, which defines grade II overt HE in the absence of disorientation to time [ 1 ]. Asterixis has also been used as an outcome in clinical trials [ 2 ]. However, limited information is available on the ability of physicians to detect/grade asterixis, and the relationship between asterixis and other clinical or quantitative HE indices. The aim of the present study was to retrospectively assess the clinical value of asterixis in a large population of well-characterised patients with varying degree of HE.
