- Forced expiratory volume in 1 s: Forced vital capacity ratio quartile cut points (lowest to highest quartile):
- Men: < 0.96, 0.96 to 1.02, 1.02 to 1.07, and ≥ 1.07
- Women: < 0.97, 0.97 to 1.03, 1.03 to 1.07, and ≥ 1.07
- CI: confidence interval
- Model 1: adjustment for demographics (age and sex)
- Model 2: Adjustment for Model 1 variables plus behaviors (cigarette smoking, physical activity, and body mass index), co-morbid conditions (diabetes, total and HDL-cholesterol and statin use, history of stroke and history of myocardial infarction), kidney function (estimated glomerular filtration rate and albuminuria), markers of inflammation (C-reactive protein), mean daytime SBP or DBP and antihypertensive medication classes being taken
