Comparison of β diversity among intestinal bacteria using weighted/unweighted UniFrac and LEfSe analyses after 6 months of intervention. (a, b) Weighted/unweighted UniFrac analysis of β diversity shows significant differences among intestinal bacteria (n = 20 per group; Kruskal–Wallis χ² test). (c, d) Results of LEfSe assays show differences in gut bacteria abundance among groups and effect size of each differentially abundant bacterial taxa (n = 20 per group; significantly different, Wilcoxon rank sum tests).
