Table 3 Odds ratios of atherosclerosis and their 95% CI when categorized by indices of periodontal disease (CPITN score, average probing depth and gingival bleeding index) before and after adjustment for age, systolic blood pressure and pack-years

From: Periodontal disease and atherosclerosis from the viewpoint of the relationship between community periodontal index of treatment needs and brachial-ankle pulse wave velocity
