- Forced expiratory volume in 1 s quartile cut points (lowest to highest quartile):
- Men: < 80.7, 80.7 to 91.8, 91.8 to 101.1, and ≥ 101.1
- Women: < 83.8, 83.8 to 95.4, 95.4 to 106.8, and ≥ 106.8
- Forced vital capacity quartile cut points (lowest to highest quartile):
- Men: < 81.4, 81.4 to 90.4, 90.4 to 99.8, and ≥ 99.8
- Women: < 83.3, 83.3 to 94.2, 94.2 to 105.2, and ≥ 105.2
- CI: confidence interval
- Model 1: adjustment for demographics (age and sex)
- Model 2: Adjustment for Model 1 variables plus behaviors (pack years of 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
