The concordance between the structural alteration of 448 OTUs and the alleviation of hypercholesterolemia phenotypes. Procrustes analysis combined the principal coordinate analysis from 448 OTUs (end of lines with big solid symbols) with the principal coordinate analysis from the lipid variables (end of lines with small solid symbols) for (a) all participants, (b) oatmeal group, (c) control group. P value was from 999 Monte-Carlo simulations. PC1, principal coordinate 1; PC2, principal coordinate 2. Oat Day 0: baseline in oatmeal group; Oat Day 45: endpoint in oatmeal group; Con Day 0: baseline in control group; Con Day 45: endpoint in control group
