Figure 1.
Beta diversity comparisons by principal coordinate analysis (PCoA) plots based on (un)weighted UniFrac distances. The percentage of explained variability of each PC is indicated on the axis. Each point represents a sample and is colored by sample types (red squares, lung cancer; green circles, healthy controls). A. PCoA based on the unweighted UniFrac distances. B. PCoA based on the weighted UniFrac distances.
