The pre- and postoperative modified Rankin Scale (mRS) grade is shown in relation to the intraoperative mean arterial blood pressure (MABP). Postoperative mRS grades are shown as circles. They are displayed in black colour in patients in which the mRS grade remained unchanged. Otherwise, arrows indicate the change from pre- to postoperative mRS grades. Patients with equal or worsened outcomes (red arrows) are shown in the upper part, and patients with equal or improved outcomes (blue arrows) in the lower part
