Treatments listed as: Low-RS-S (diet with amylopectin corn starch), Low-RS-WG (diet with dent whole-grain corn flour), Hi-RS-S (diet with high amylose starch), and Hi-RS-WG (diet with high amylose whole-grain corn flour).
Statistical differences were: bacteroidetes (p < 0.0001, Low-RS-S versus Hi-RS-S, Hi-RS-WG versus Hi-RS-S, Low-RS-WG versus Hi-RS-S); and firmicutes (p < 0.0001, Low-RS-WG versus Hi-RS-WG). The p < 0.05 value was divided by 6 as a Bonferoni adjustment.
