A multivariate regression analysis was used to examine the association between environmental conditions and phylogenetic diversity of salivary microbiome of individuals with ≥9 teeth (n = 2,080).
Abbreviations: BMI, body mass index; DT, decayed teeth; DFT, decayed and filled teeth; PPD, periodontal pocket depth; BOP, bleeding on probing.
