  • Note: CT = computed tomography, ICU = intensive care unit, IQR = interquartile range.

  • * Except where noted otherwise.

  • Done in the absence of any documented neurologic change.

  • E.g., extended length of stay, administration of antiplatelets for vascular dissection.

  • § Owing to clinical deterioration within 72 hours in all cases.
