(a) Principal coordinate analysis (PCoA) with weighted UniFrac distance matrixes for bacterial communities associated with the three health statuses. (b) Principal component analysis (PCA) of the dominant genera between samples from healthy patients and patients with periodontitis. Only genera with ≥ 1% mean relative abundance across all samples are shown.
