Figure 1

Alpha rarefaction plot demonstrating phylotype diversity in subgingival plaque samples. Shown are the numbers of different Operational Taxonomic Units (OTUs) as a function of the numbers of sequences analyzed and generated with QIIME. OTUs that occur less than 150 times/sample are not included. C, cognitively impaired, not dementia; D, dementia; N, normal.
