Four human volunteers participated in this study. Faecal samples were obtained after the subjects drank water for 14 days (washout-1 or washout-2) and ate α-cyclodextrin (αCD) or indigestible dextrin (DEX) for seven days.
The values show the mean ± standard deviation.
No statistical difference was detected between faecal samples (washout-1, αCD, washout-2, and DEX) in terms of observed operational taxonomic units (OTUs), Chao1, Shannon index, and Simpson index (Kruskal-Wallis test).
