Beta diversity and alpha diversity at the phylum or species level A. PCA analysis at the phylum level. B. The NMDS analysis at the phylum level. C. The ANOSIM of NMDS analysis at the phylum level. D. Pielou index at the phylum level between periodontitis and control samples. E. Shannon index at the phylum level between periodontitis and control samples. F. Simpson index at the phylum level between periodontitis and control samples. G. Simpson index at the species level between periodontitis and control samples. All P values were calculated by Wilcoxon rank sum test. PCA, Principal component analysis; NMDS, non-metric multidimensional scaling; ANOSIM, analysis of similarities.
