of borderline significanceP = 0.052
Salivary MPO concentrations associated in all models (1–3) with increased odds for having the risk haplotype and reached a statistical significance (strongest in Model 3) with an OR of 1.372 ( P = 0.007) per increase of logarithmically transformed unit. The association of CRS was of borderline significance with an OR of 1.793 ( P = 0.052) (model 1) and OR of 1.831 ( P = 0.054) (model 2) for the change from low to moderate/high risk of having periodontitis.
