Beta diversity analysis by unweighted UniFrac principal coordinate analysis. Unweighted principal coordinate analysis (PCoA) plot is shown comparing Helicobacter pylori (H. pylori) patients (blue, n = 19) to control subjects (red, n = 16). Significant differences between H. pylori patients and control subjects were identified by unweighted UniFrac PERMANOVA (F = 2.523, P = 0.001). The proportion of variance explained by each principal coordinate axis is denoted in the corresponding axis label; PCo1 explains 16.95% of the variability and PCo2 explains 9.13% of the variability. H. pylori: Helicobacter pylori.
