Figure 2.
16S rRNA gene amplicon-based relative bacterial abundance in CID 1 (baseline) and CID 5 (post-intervention) samples. Relative abundances are shown for the 10 most abundant bacterial taxa at (A) phylum and (B) genus level. Data shown are for all 168 samples (i.e., CID 1 and CID 5 pairs from 84 participants). “Other” refers to less abundant taxa and those not classified at the respective taxonomic level. HP-NB, higher-protein nut bar; HC-CB, higher-carbohydrate cereal bar.
