Comparisons between cfPWV and baPWV (25, 110–112).

	cfPWV	baPWV
Strength	Includes only elastic arteries More abundant clinical data, and most validated Considered as gold standard a measure of arterial stiffness Widely used worldwide	Simple to measure Convenient to patients Useful in mass screening
Limitation	The measurement needs technical skill The measurement causes discomfort Less useful in mass screening	Includes both elastic and muscular arteries Invalid height-based formula to estimate arterial path length Inaccurate in patients with peripheral arterial stenosis or aortic disease Mainly used in Asian countries
