Figure 4
Panel A shows the phase shift between BPR minimum and BFVR minimum and the phase shift between BPR maximum and BFVR maximum for the right MCA for the □ normotensive and hypertensive groups and ■ for the non-stroke side MCA in the stroke group. Figure 4B shows the phase shift between BPR minimum and BFVR minimum and the phase shift between BPR maximum and BFVR maximum for the left MCA for the normotensive, and hypertensive groups and for the stroke side MCA in the stroke group. Phase shift was greater in the normotensive compared to other groups (between group comparisons *** p < 0.005, ** p < 0.01 *p < 0.05, mean ± SE).
