(A) Robust Aitchison PCA plot of metagenome samples processed through HUMAnN and DEICODE and visualized with qurro. Pathways not present in at least 50% of samples were removed from the analysis. These values Separation of Control and Metformin treated groups was significant (p-value 0.012). (B) Corresponding log-ratio rankings for Pathways oriented to Axis 1 (right), displaying only pathways contributed by Bacteroides spp. Numerator (red)/Denominator (blue) ratios of these pathways were computed to generate a box-whisker plot (left), p-value 0.008. These results were corroborated with songbird analyses.
