Comparison of the salivary microbiome composition between the NC− (n = 11), NC+ (n = 10), OLP− (n = 9), and OLP + (n = 21) groups. a Observed species, b Chao diversity index, c Ace diversity index, d Simpson’s diversity index, and (e) Shannon’s diversity index between the NC− and NC+ groups, as well as between the OLP− and OLP+ groups. Principal coordinate analysis (PCoA) plots of unweighted UniFrac distances of saliva microbiota between the NC− and NC+ groups (f) and between the OLP− and OLP+ groups (g). *p < 0.05; **p < 0.01; ns, no significance
