  • *Adjusted for admission NIHSS, patient sex, tPA administration, symptomatic intracranial haemorrhage and admission glucose value.

  • BPV, blood pressure variability; CV, coefficient of variation; mRS, modified Rankin Scale; NIHSS, National Institutes of Health Stroke Scale; SBP, systolic blood pressure; SV, successive variation; tPA, tissue plasminogen activator.
