  • Note:—IA-tPA indicates intra-arterial tissue plasminogen activator.

  • a P values reported using the Fisher exact test for categoric variables and the Wilcoxon-Mann-Whitney rank sum test for continuous variables (age, NIHSS score, and time-to-event data).

  • b Symptom onset or from the time when the patient was last seen neurologically well to the time of CT.

  • c Time from symptom onset or from the time when the patient was last seen neurologically well to the time of intervention with any form of IAT.
