Multivariable logistic regression analysis of hyperperfusion syndrome after carotid stenting.

*p**pOR: odds ratio, CI: confidence interval, 3 h SBP after CAS: mean systolic blood pressure after carotid artery stenting within 3 hours, TTP index: time to peak index = [(ipsilateral TTP−contralateral TTP)/contralateral TTP], rCBV index: regional cerebral blood volume index = [(ipsilateral rCBV−contralateral rCBV)/contralateral rCBV], Δx2 (increment of chi-square) at steps 2 and 3 represent the statistical significance of any improvement in prediction as a result of that variable being entered into the model, AUROC: area under the receiver operating characteristic curve.
