Table 5 presents pairwise comparison of TCD including , , , PI, and RI among groups 1, 2, 3, and 4 before treatment. indicates comparison between group 1 and group 2, means comparison between group 1 and group 3, compares group 1 and group 4, refers to a comparison between group 2 and group 3, indicates a comparison between group 2 and group 4, and means comparison between group 3 and group 4. Group 1 is healthy controls group, group 2 is cirrhosis without HE group, group 3 is cirrhosis with MHE group, and group 4 is cirrhosis with OHE group. Pairwise comparisons between multiple groups were performed using SNK-q or LSD-t method of ANOVA. means significant differences in an index between two groups.
