Mean (± SE) telomere length (T/S ratio) by exercise capacity.

*Model 1 = Adjusted for age, sex, race, education.Model 2 = Model 1+hypertension, heart failure, stroke, diabetes, left ventricular (LV) ejection fraction, and chronic lung disease.Model 3 = Model 2+angiotensin system inhibitor, statin, ASA.Model 4 = Model 3+smoking, BMI, physical inactivity, and depressive symptoms.

*模型1（Model 1）：已针对年龄、性别、种族与受教育程度进行校正。模型2（Model 2）：以模型1为基础，额外纳入高血压、心力衰竭、脑卒中、糖尿病、左心室射血分数（LV）及慢性肺部疾病作为校正变量。模型3（Model 3）：以模型2为基础，额外纳入血管紧张素系统抑制剂、他汀类药物与阿司匹林（ASA）作为校正变量。模型4（Model 4）：以模型3为基础，额外纳入吸烟史、身体质量指数（BMI）、体力活动不足及抑郁症状作为校正变量。
