| ≥70% | 0.78 (0.67–0.92) | 0.79 (0.67–0.93) | 0.83 (0.70–0.99) |
| Association of LTPA with ECAS | |||
| Characteristic | Model 1 | Model 2 | Model 3 |
| β-Estimate (95% CI) | β-Estimate (95% CI) | β-Estimate (95% CI) | |
| Number of carotid plaques | −0.02 (−0.06–0.02) | −0.01 (−0.03–0.45) | −0.01 (−0.05–0.04) |
| cIMT | 0.002 (0.001–0.003) | 0.003 (0.002–0.005) | 0.004 (0.002–0.005) |
LTPA = leisure time physical activity; OR = odds ratio; CI = confidence interval; ICAS = intracranial artery stenosis; ECAS = extracranial carotid artery stenosis; cIMT = carotid intima-media thickness
Model 1: adjusted for age, sex, race and ethnicity, high school completion, and insurance status
Model 2: model 1 additionally adjusted for body mass index, hypertension, diabetes mellitus, hyperlipidemia, current smoking
Model 3: model 1 additionally adjusted for body mass index, systolic and diastolic blood pressure, years of hypertension, number of anti-hypertensive medications, blood glucose, years of diabetes mellitus, number of anti-glycemic medications, low-density lipoprotein, high-density lipoprotein, triglycerides, statin use, years smoked, and packs per day.
