Effects of periodontal disease indicators on risk of diabetes, obesity, IGT, COPD, and ASCVD. Model 1 (M1) is the reference model based on healthy employees with HbA1c < 5.7. Model 2 (M2) is M1 adjusted for age, and Model 3 (M3) is M1 adjusted for age and smoking status. Multiple logistic regression analysis was used to obtain the odds ratio. The number of patients with disease is as follows: Diabetes; n = 87, Obesity; n = 348, IGT; n = 117, COPD (moderate); n = 464, ASCVD; n = 93. Markers indicate estimated odds ratio (OR). Vertical ranges indicate 95% confidence interval (CI).TN; Number of teeth
