BFV, blood flow velocity; CVR, cerebrovascular responsiveness; L, left side; R, right side; P, significance of difference between means.
a
Wilcoxon Signed Rank test (all other continuous variables were evaluated using the paired samples t-test). P-values in bold indicate a statistically significant difference (P < 0.05) between the left and right middle cerebral artery.
