Figure 6
Beta diversity (A–D) and alpha diversity (E–J) of 40 subgingival plaque samples. For beta diversity, Jaccard index (A,C) and Bray–Curtis index (B,D) are shown. Samples were clustered based on principal coordinates analysis (PCoA). In (A,B), samples were highlighted by smoking group, and in (C,D), samples were highlighted based on periodontal condition. PCo1, PCo2 and PCo3 are shown in the figures. The percentage of variation explained by each principal coordinate is indicated on the axes. Each point represents a microbial community from one sample. For alpha diversity (E–J), samples were grouped based on both smoking status and periodontal condition.
