Note:— VT indicates vascular territory; CE, cardioembolism; LAA, large-artery arterosclerosis; SAO, small-artery occlusion; AC, anterior circulation; PC, posterior circulation.
P values by the Fisher exact test:
* P < 0.05;
** P < 0.01;
*** patients with DW/MR imaging lesions <15 mm were classified as SAO by definition, P < 0.001.
