↵a Unless otherwise indicated, values represent the number of aneurysms (%) or median [interquartile range]. Not all percentage totals reach 100% because of rounding.
↵b Patients with a history of both ischemic and hemorrhagic stroke were counted in each category.
↵c Renal dysfunction was defined as an eGFR of <45 mL/min/1.73 m2.
↵d P < .05.
↵e History of allergy included allergy to any food or drug.
