Risk of peripheral arterial disease in different tertiles of leukocyte mean telomere length.

PAD indicates peripheral arterial disease; CI, confidence interval.*Odds ratio and 95%CI were obtained with multivariate conditional logistic regression analysis.†Model I: Adjustment for body mass index, systolic and diastolic blood pressure, smoking, alcohol intake, fasting glucose, triglycerides, total cholesterol, HDL cholesterol, and LDL cholesterol.‡Model II: Adjustment for the covariates mentioned above plus diabetes, history of hypertension, previous cardiovascular disease, and medication treatment.§Model III: Adjustment for individual genetic variants rs2735940 and rs2853669 of the hTERT gene, except for the covariates mentioned in Model II.
