Fig. 5From: Subgingival microbiome of deep and shallow periodontal sitesĀ in patients with rheumatoid arthritis: a pilot studySimiliarities between shallow and deep subgingival microbiome within subjects in RA and non-RA controls. aĀ Weighted and bĀ unweighted UniFrac distances between paired deep and shallow samples were calculated for each subject and then compared between RA and non-RA controls. The smaller the intra-subject UniFrac distance (y-axis), the more similar the paired samples are to each another. Each subject is shown as a single open circle. Boxplots show the median distance and their interquartile range (IQR). Whiskers extend to 1.5 times the IQR. P values were estimated using unpaired t-testsBack to article page
