Depicted values are the results of multivariable linear regression analyses, which were performed separately for each phase. Several covariables were used for adjustment and are omitted here for clarity. The full regression models are shown in Supplementary Tables 5 and 6. β depicts the change of NIHSS score after 24 h per mm Hg increase
