Arabinoxylan alters the global composition of fecal bacterial communities and induces distinct shifts in taxa. a Non-metric multidimensional scaling (NMDS) plot based on Euclidean distance metrics of arabinoxylan and microcrystalline cellulose groups at each time point (inter-subject β-diversity) showing changes in the distance between subjects over time. Euclidean distances b between fecal microbiotas of subjects at each study time point (inter-subject) and c between each subject’s fecal microbiota at baseline and during W1 and W6 of treatment (intra-subject). d α-Diversity (displayed as Shannon index and total OTUs) of the fecal microbiotas of subjects at each time point. e Absolute change (ΔW6–BL) in relative abundance of bacterial taxa affected by the dietary intervention. Data analyzed using PERMANOVA for a, GEE models (with Bonferroni correction) for b and d, and Mann–Whitney tests for c. For e, data were analyzed using either Wilcoxon tests to assess within-group changes relative to baseline, or Mann–Whitney tests to assess between-group changes (i.e., AX vs. MCC; with FDR correction). β-diversity and compositional data were reported as mean ± SD, and centered log-ratio transformed prior to the statistical analyses.
