The α-diversity and β-diversity in hemodialysis patients with and without β blocker used in full cohort (A,B) and propensity score matching cohort (C,D). β blocker users had a higher α-diversity than β blocker nonusers in full cohort (A) and propensity score matching cohort (C) β blocker users had a different β-diversity (Bray–Curtis index) compared to β blocker nonusers in full cohort (B) and propensity score matching cohort (D). The β-diversity p-value was calculated using the homogeneity of group dispersions by the Permutational Analysis of Multivariate Dispersions (PERMDISP) test.
