BP, blood pressure; ER, emergency room; SBP, systolic blood pressure; MAP, mean arterial pressure.
Age, sex, NIHSS score in the acute setting, congestive heart failure, diabetes mellitus (type 1 and type 2) and history of ischemic stroke (IS) were used as covariates. In the analyses of ΔSBP and ΔMAP, SBP and MAP, respectively, were also included as covariates.
