aThe P value for gender distribution in the two groups was obtained by Chi-square test.
bThe P value for age and neuropsychological tests difference between the two groups was obtained by two sample t test.
Values are expressed as mean ± SD. NCT-A = number connection test type A; DST = digit symbol test; HC = healthy control; MHE = minimal hepatic encephalopathy; non-HE = non-hepatic encephalopathy.
