Abstract
Minimal hepatic encephalopathy, defined by the portosystemic hepatic encephalopathy score (PHES), is associated with a higher risk of subsequent OHE. It remains unclear if there is a stepwise increase in OHE risk with worse PHES results. In this multicenter study, patients with minimal hepatic encephalopathy, as defined by abnormal PHES, were followed for OHE development. In all, 207 patients were included. There was no stepwise increase in OHE risk with worse PHES results. Abnormal PHES is associated with a higher OHE risk, but we found no stepwise increase in OHE risk with worse PHES results below the established cutoff.
