  1. In the weighted multivariable logistic regression models, the reference group was participants with stage I periodontitis. The outcome variables were circadian syndrome and the seven components of circadian syndrome. Model 1: adjusting periodontitis stage, age, sex and race. Model 2: adjusting periodontitis stage, age, sex, race, educational levels, family income, marital status, smoking status, drinking status, physical activity, and dietary quality. Model 3: adjusting periodontitis stage, age, sex, race, educational levels, family income, marital status, smoking status, drinking status, physical activity, dietary quality, working condition, working hours and taking medicines status. Data are shown as OR and 95% CI. Significant values are shown in bold
  2. Abbreviations: CI Confidence interval, OR Odds ratio, FPG Fasting Plasma Glucose, HDL High-density lipoprotein cholesterol, TG triglycerides
