The paired sample t test (α = 0.05) results of reflection amplitude (RA), reflection phase (RP), transmission amplitude (TA) and transmission phase (TP) among three time points (before bilateral carotid artery ligation, 3 h after ligation and 6 h after ligation). a is RA and b represents RP. The results of TA and TP are shown in c and d. The number of symbol (*) reflects the size of P value. Symbol (***) indicates extremely significant (P < 0.001)
