Figure 1.

Bray-Curtis principal coordinate analysis (PCoA) plot for subgingival microbiome profiles. Axis one accounts for 13% of sample variance, while axis two and three account for 9% and 8% of variance, respectively. One dot represents one sample in each group. This plot demonstrates clusters of samples based on their similarity of microbial composition. These three groups display distinct microbial compositions. (H (green): healthy; P (red): periodontitis before non-surgical therapy; A (blue): periodontitis after non-surgical therapy).
