Ordination of oral rinse microbial communities in healthy individuals and patients with tonsillitis. a Principal component analysis (PCA) of centered log ratio-transformed exact sequence variant (ESV) counts. Each circle represents community composition of one sample; the closer two dots are the more compositionally similar their microbial communities. b Three dimensional representation of PCA in panel A, with spokes connecting samples to their respective centroids according to cohort (healthy or tonsillitis). c Principal coordinate analysis (PCoA) of weighted UniFrac distances calculated in QIIME 2. Green circles represent samples from non-tonsillitis individuals, orange circles represent samples from patients with tonsillitis. Community composition of samples from tonsillitis patients and healthy individuals significantly differed irrespective of metric used (transformed ESV counts and weighted UniFrac) (p < 0.001, PERMANOVA)
