VWF and migraine with aura: In this cross‐sectional study, we found higher VWF:Ag levels in all groups—ischemic stroke (group 1), migraine with aura (group 2), and ischemic stroke and migraine (group 3)—compared with the reference group (group 4), with 31% higher levels in the ischemic stroke and migraine group (group 3), statistically significantly higher than in the groups with only stroke (group 1) or only migraine with aura (group 2).
