Comparison of flow propagation velocity measurements by three methods

	Front of aliased velocity	Black-to-colour transition	Main aliased velocity
Controls	54.8 (5.5)	55.5 (17.7)	72.1 (40.6)
Patients	69.9 (13.5)	144.1 (110.0)	137.2 (116.0)
P:	< 0.002	< 0.02	0.08 (NS)
R:	-0.57 (-0.79 – -0.23)	-0.43 (-0.7 – -0.04)	-0.19 (-0.54 – 0.22)

P: significance of the differences between the two groups (Standard deviation in parentheses). R: Correlation with strain rate propagation velocity (95% confidence intervals in parentheses).
