Data are OR (95% CI) values. The ORs of IABPs in model 1 were adjusted sex, age, body mass index, hypertension, diabetes mellitus, hypercholesterolemia, smoking, alcohol intake, coronary artery disease, metabolic syndrome, left ventricular hypertrophy, National Institutes of Health Stroke Scale score, and brachial-ankle pulse wave velocity. In model 2, the ORs of IABPs were adjusted for model 1 plus significant laboratory and imaging factors (white blood cell count, total cholesterol, low-density lipoprotein, thrombolysis, cerebral atherosclerosis, and high-grade white matter hyperintensities). Model 3 included sex, age, and covariates that were significantly associated with END in univariate logistic regression (p<0.1).
*p<0.05, †p<0.1.
END: early neurological deteriorat, IABP: interarm blood pressure difference, OR: odds ratio, IADBD: interarm diastolic blood pressure difference, IASBD: interarm systolic blood pressure difference.
