Dependent variable, 1: periodontal disease in 2011, 0: periodontally healthy in 2011. Model 1: continuous variable of serum antibody titer against Pg was included. Model 2: categorical variable of serum antibody titer against Pg was included. < 0.05, < 0.01. Adjusted by age, smoking, toothbrushing frequency, triglycerides, HDL, fasting glucose, and systolic blood pressure in 2003. Continuous variable of leukocytes was used, because of small number of elevated leukocytes. HsCRP, high-sensitive C-reactive protein; PR, prevalence ratio; CI, confidence interval.
