Receiver operating characteristic analysis of hemodynamic parameters to diagnose carotid web versus mild/moderate atherosclerotic stenosis based on logistic regression adjusted for degree of stenosis

Variable model	pAUC	95% CI
rAUC total	0.957	0.897 to 1.000
rAUC WI	0.631	0.422 to 0.841
rAUC WO	0.741	0.568 to 0.914
rFWHM	0.867	0.737 to 0.996
rTTP	0.631	0.427 to 0.836
rMS	0.600	0.364 to 0.836

AUC, area under the curve; FWHM, full width at half maximum; MS, maximum slope during wash in; pAUC, predictive area under the curve; r, relative (normalized to distal common carotid); TTP, time to peak; WI, wash in; WO, wash out.
