Figure 4.

Panel A shows the phase shift between BP_R minimum and BFV_R minimum and the phase shift between BP_R maximum and BFV_R 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 BP_R minimum and BFV_R minimum and the phase shift between BP_R maximum and BFV_R 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).
