Fig. 3From: Comparing dental plaque microbiome diversity of extrinsic black stain in the primary dentition using Illumina MiSeq sequencing techniqueUnweighted Unifrac PCoA analysis. For each sample, the first two principal coordinates (PCo1 and PCo2) from the principal coordinate analysis of weighted UniFrac are plotted. The variance as calculated by PCoA is indicated in parentheses on the axes. BP: Plaque samples from EBS-positive subjects. BFP: Plaque samples from EBS-free subjectsBack to article page
