Fig. 2From: Gut microbiota modulation with long-chain corn bran arabinoxylan in adults with overweight and obesity is linked to an individualized temporal increase in fecal propionateArabinoxylan 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.
