Phylogenetic Weighted UniFrac distances were used to explain β-diversity across diet groups. Differences between the samples were tested by the permutational multivariate analysis of variance (PERMANOVA): samples are colored and grouped by their corresponding diet group into ellipses representing 95% confidence intervals. (a) in the female cohort, pseudo-F-value = 12.845; p-value < 0.001. All diet groups were statistically different from one another; (b) in the male cohort, pseudo-F-value = 14.751; p-value < 0.001. All diet groups were statistically different from one another.
