Table 2 Proportions of different stroke subtypes classified according to the Chinese Ischemic Stroke Subclassification (CISS) criteria in 968 acute cerebral infarction (ACI) patients with and without migraine respectively and cerebral locations of ischemic infarction in different stroke subtypes

From: Association between ischemic stroke and migraine in elderly Chinese: a case–control study

  ACI patients with migraine (n = 166) ACI patients without migraine (n = 802)
Subtype Overall frequency Anterior circulation Posterior circulation Overall frequency Anterior circulation Posterior circulation
LAA 65.06%* 63.89% (69/108) 36.11% (39/108) 86.16% 65.12% (450/691) 34.88% (241/691)
CS 23.50%* 66.67% (26/39) 33.33% (13/39) 8.35% 73.13% (49/67) 26.86% (18/67)
PAD 6.02% 80.00% (8/10) 20.00% (2/10) 2.62% 71.43% (15/21) 28.57 (6/21)
OE 3.61% 66.67% (4/6) 33.33% (2/6) 1.87% 66.67% (10/15) 33.33% (5/15)
UE 1.81% 100% (3/3)* 0% (0/0) 1.00% 87.50% (7/8) 12.50% (1/8)
  1. LAA Patients with large artery atherosclerosis, CS Cardiogenic stroke, PAD Penetrating artery disease, OE Other etiology, and UE Undetermined etiology. A single asterisk (*) denotes that the difference in the same variable for the same stroke subtype was significant between ACI patients with migraine and ACI patients without migraine at α = 0.05.
