- Advanced periodontitis is defined as periodontal pocket ≥ 6.0 mm. Atherosclerosis is defined as carotid intima-media thickness (CIMT) ≥ 1.1 mm. Model 1: adjusted only for sex and age. Model 2: adjusted further for smoking status (never, former, current), number remaining teeth, status of decayed teeth (presence, absence), body mass index (BMI), HDL-cholesterol, triglycerides, hemoglobin A1c (HbA1c), reticulocyte count, and CIMT. Model 3: adjusted further for antihyerlipidemic medication use (yes, no) and glucose-lowering medication use (yes, no)
