Alpha and beta diversity of gut microbiota in patients with cirrhosis, before and after lactulose. Legend: a: Principal co-ordinate analysis of weighted UniFrac distances between faecal specimens collected from patients with cirrhosis before (red) and after (blue) lactulose administration. b: Comparison of weighted UniFrac distances between individual pre-lactulose specimens from different patients (left, in blue) and between paired (pre- and post-lactulose) specimens from each patient (right, in red); the latter distances were significantly less (p < 0.001) than the former. c: Comparison of measures of alpha diversity between specimens from patients with cirrhosis collected before (red) and after (blue) lactulose administration. The p values shown were obtained using Mann-Whitney U test with Bonferroni correction
