Small intestinal microbiota changes and correlation of changed intestinal microbiota after a 2-week AOS dosing. a The PLS-DA of the microflora in different treatments. b Differences of bacterial abundance at the phylum level. c Cladogram. d LDA distribution. Linear discriminate analysis effect size (LEfSe) was performed to determine the difference in abundance; the threshold of LDA score was 4.0 (n = 15 samples/group). e Correlation of intestinal microbiota and blood metabolites. (n = 10 samples/group)
