Key result
The reduction in the radial pulse wave inflection point was significantly related to both EDV (r=-0.41) and EIDV (r=-0.42) measured by the invasive forearm technique (P<0.05).

Pulse wave inflection reduction associates with invasive EDV/EIDV; leaves open its specificity versus other methods and clinical utility.
Cross-Sectional (n=24)
How do four different methods for measuring endothelium-dependent vasodilation in the human peripheral circulation correlate with each other in young, healthy subjects?
Effect estimate: r=-0.41 and r=-0.42
p-value: p=<0.05
Different methods of measuring endothelium-dependent vasodilation do not correlate well, suggesting that endothelial function differs between conduit and resistance arteries and that the pulse wave technique is not specific to EDV.
Lind et al. (2002) conducted a cross-sectional in Healthy (n=24). Four methods to measure endothelium-dependent vasodilation was evaluated on Correlation between measurement techniques for endothelium-dependent vasodilation (r=-0.41 and r=-0.42, p=<0.05). The reduction in the radial pulse wave inflection point was significantly related to both EDV (r=-0.41) and EIDV (r=-0.42) measured by the invasive forearm technique (P<0.05).
