Differences in the composition of treponeme OTUs belonging to phylogroups 1–7 that were detected in the periodontitis and periodontitis-free subject groups were determined using ∫ − libshuff, unweighted UniFrac, weighted UniFrac and parsimony p-test approaches. UW UniFrac = unweighted UniFrac; W UniFrac = weighted UniFrac. Significance: ns = p > 0.05; * = p < 0.05; ** = p < 0.01; *** = p < 0.001; ns = not significant.
