Table 2.

Wall shear stress and wall thickness in the symptomatic carotid artery with (cases) and without (controls) new ulcerations at follow-up.

	New ulceration present (n = 6)	New ulceration absent (n = 12)
Parameters	Median [IQR]	Median [IQR]	p value
Minimum wall shear stress (Pa)	0.5 [0.4–0.8]	0.3 [0.2–0.4]	0.083
Maximum wall shear stress (Pa)	9.9 [6.6–18.5]	13.6 [9.7–17.7]	0.349
Maximum oscillatory shear index	0.04 [0.01–0.10]	0.12 [0.06–0.20]	0.019
Maximum relative residence time (Pa−1)	1.25 [0.78–2.03]	2.93 [2.03–5.28]	0.011
Maximum wall thickness (mm)	4.1 [3.6–4.25]	4.0 [3.55–4.52]	0.888

Maximum is the 95th percentile of the data except for wall thickness.
