| Multiple vascular territory (n=432) | 32.6 | 0.0 | 32.2 | 6.7 | 4.4 | 21.3 | 2.8 | |
| Carotid territory (n=1606) | <0.001 | |||||||
| Single vascular territory (n=1502) | 38.5 | 22.8 | 21.7 | 1.7 | 3.7 | 10.2 | 1.4 | |
| Multiple vascular territory (n=104) | 25.0 | 0.0 | 44.2 | 4.8 | 5.8 | 19.2 | 1.0 | |
| Vertebrobasilar territory (n=914) | <0.001 | |||||||
| Single vascular territory (n=768) | 37.8 | 35.8 | 12.0 | 3.3 | 2.3 | 7.2 | 1.7 | |
| Multiple vascular territory (n=146) | 52.1 | 0.0 | 23.3 | 6.2 | 2.7 | 14.4 | 1.4 |
Values are percentages of patients. CE indicates cardioembolism; Incomplete, incomplete evaluation; LAA, large‐artery atherosclerosis; Negative, negative evaluation; OD, other determined etiology; SVO, small vessel occlusion; Two or more, two or more causes identified.
*
P values were obtained from comparisons of vascular territory multiplicity according and distribution of stroke subtypes using Pearson chi‐square tests or Fisher's exact tests when appropriate.
