- Values denote as number (raw percentage) for categorical variables and mean ± standard deviation (SD) for continuous variables
- p-values were obtained from T-test for continuous variables and chi-square test for categorical variables
- Bold denotes statistical significance at p < 0.05
- OHRQoL: Fair denotes OHIP-14K < 3: never, hardly ever, occasionally; Poor denotes OHIP-14K ≥ 3: fairly often, very often
- Smoking: “No” denotes to never smoked, “Yes” denotes to past and current smoker
- Alcohol drinking: “No” denotes to drunken, “Yes” denotes to past and current drinker
- Metabolic syndrome: “No” refers to two or less factors, “Yes” refers to three or more factors among five factors: Obesity (body mass index (body kg/height m2) ≥ 25); Total triglyceride ≥ 150 mg/dL; HDL cholesterol: Male < 40 mg/dL, Female < 50 mg/dL or medication for dyslipidaemia; Hypertension: systolic blood pressure ≥ 130 mmHg or diastolic blood pressure ≥ 85 mmHg or medication for hypertension; Glycated hemoglobin ≥ 5.3% or medication for diabetes
- Periodontitis: followed by guideline “Staging and grading of periodontitis: Framework and proposal of a new classification and case definition” [51] classified into 2 groups: No (healthy or stage I–II) and Yes (stage III–IV)
