  1. Model 1, model covariates were age, sex, and ethnicity.
  2. Model 2, model covariates were model 1 plus marital status, education.
  3. Model 3, model covariates were model 2 plus smoking, body mass index, total cholesterol/high density lipoprotein cholesterol, eGFR, and diabetes.
  4. Model 4, model covariates were model 3 plus mean arterial pressure.
  5. Model 5, model covariates were model 4 plus white blood cell, monocyte, neutrophil, and lymphocyte.
  6. OR(95% CI), odds ratio and 95% confidence interval; PD, probing depth; CAL, clinical attachment loss.
  7. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
