Liver-transplant-free survival in the entire patient cohort as well as stratified for grade of hepatic encephalopathy. Liver-transplant (LTX)-free survival following fulfillment of acute liver failure (ALF) criteria is shown as Kaplan-Meier graphs for all patients (A), and stratified by the grade of maximum hepatic encephalopathy (HE) (B) for a 28-day follow-up. p-values < 0.05 were considered significant
