Fig. 4

Mean proportional bacterial abundance changes at (a) the family level for the Prevotella-plus group (Prevotellaceae p = 0.002, Bifidobacteriaceae p = 0.0002, Bacteroidaceae p = 0.004) and (b) Prevotella-minus group (Bifidobacteriaceae p < 0.0001) during maltodextrin, AXOS supplementation and washout periods. Mean proportional abundance of (c) Prevotella spp. (Prevotella-plus group genus level, increased during AXOS supplementation p = 0.002), (d) Bacteroides spp. (Prevotella-plus group genus level, decreased during AXOS supplementation p = 0.004), and (e) Bifidobacterium spp. (Prevotella-plus group genus level, increased during AXOS supplementation p = 0.0001, Prevotella-minus group, AXOS p < 0.0001) during the maltodextrin, AXOS and washout periods. *p ≤ 0.01, significance from LEfSe analysis comparing across all three supplement periods
