Comparison of cognitive testing between patients with and without HE within each group. Patients with HE performed worse than those without HE in both Alc and Nalc groups.

^*p<0.05

^**p<0.005 no-HE vs. HE (within each group); data is presented as Mean±SEM; a high score on block design, digit symbol and inhibitory control targets and a low score on the rest indicate poor cognition.

HE: prior overt hepatic encephalopathy, No-HE: no history of overt hepatic encephalopathy
