Figure 2From: High throughput DNA sequencing to detect differences in the subgingival plaque microbiome in elderly subjects with and without dementiaTaxonomic assignments found in subgingival plaque clustered by cognitive status. Counts for each OTU that was identified more than 150 times/sample were included in this analysis. The total height of the bar represents 100% of the assigned sequences after quality filtering, and the size of the colored regions represents proportional contributions of each phylotype shown. For clarity, only major families (>3%) are listed in the color key. OTU, Operational Taxonomic Units.Back to article page
