Comparison of subgingival microbiome according to probing depth and RA status. Principal Coordinates Analysis (PCoA) was conducted using weighted and unweighted UniFrac distances. PCoA on weighted UniFrac distances were used to examine community structure according to aĀ probing depth and bĀ RA status. PCoA on unweighted UniFrac analysis were used to visualize the relationship between cĀ probing depth or dĀ RA status and community membership. Variation explained by each axis is shown in brackets. lues were estimated using Permutatinal Multivariate Analysis of Variance (PERMANOVA) with 999 permutations
