Fig. 3From: Subgingival microbiome of deep and shallow periodontal sitesĀ in patients with rheumatoid arthritis: a pilot studyDifferentially abundant OTUs between deep and shallow sites in RA subjects. Differentially abundant taxa were identified using LEfSe and met the minimum LDA score of 2. OTUs enriched in deep sites are shown in red, whereas OTUs more abundant in shallow sites are shown in dark blue. OTU: Operational taxonomic unitBack to article page
