Comparison of receiver operating characteristic (ROC) curves of FTc(W), FT, 1/DSIFTc, and FTc(B) to predict PIH. FT, carotid flow time; FTc(W), carotid flow time corrected by Wodey’s equation; FTc(B), carotid flow time corrected by Bazett’s equation; and DSIFTc, Doppler shock index with FTc in the denominator
