Furthermore, over the course of the maintenance phase (W10 versus W2), the Observed and Chao1 alpha-diversity indices (richness) showed a trend of decrease in both groups, while the Shannon and Inv-Simpson indices (evenness) significantly decreased in the control group (Fig. 4 F and Supplementary Table S14), but the intergroup difference was not significant.
