Figure 2.

Double-hierarchical clustering analysis. The samples from 45 subjects and 83 dominant genera are represented on a double-hierarchical clustering heat map. The blue and red squares represent lower and higher abundances, respectively. The clusters on the right side indicate the similarity among the individual (IDs on the left side) profiles at the genus level. A frame at the left represent the samples forming a dominant cluster. Open arrows indicate the FD subjects with samples showing the Bacteroidetes < Proteobacteria phylum pattern. The clusters at the bottom indicate the genera showing similarity in the frequency of identification among samples. See supplementary figures S2 and S3 to view the names of the genera in this figure.
