Note.—AICA indicates anterior inferior cerebellar artery; ALB, anterolateral group from the basilar artery; AMB, anteromedial group from the basilar artery; LB, lateral group from the basilar artery and anterior inferior cerebellar artery; MSCA, medial branches of the superior cerebellar artery; LPICA, lateral branches of the posterior inferior cerebellar artery; LSCA, lateral branches of the superior cerebellar artery; and MPICA, medial branches of the posterior inferior cerebellar artery.
* The Mann-Whitney U test was used for the comparisons.
