  1. Values are presented as number (%); BA, basilar artery; VBA, vertebrobasilar artery;
  2. Walking vs. Tuning Fork, p ≤ 0.001; Walking vs. Lambda, p = 0.001; Walking vs. No Confluence, p = 0.211; Tuning Fork vs. Lambda, p = 0.037; Tuning Fork vs. No Confluence, p = 0.018; Lambda vs. No Confluence, p = 0.332; the significant level was adjusted to p’, p’ = p/m, m = k (k-1)/2 + 1, k indicates the group number, and p’ < 0.007 considered to be statistically significant
