Computational Microvascular Model Parameters for PAD Treadmill Completers and Noncompleters

Variable	Completers	Noncompleters	P value
k t , 1/s	6.15 (4.39–7.91)	8.13 (6.41–9.85)	0.10
K tissue, m2	3.72 (3.44–4.00)	4.98 (4.70–5.25)	<0.001
φ	0.53 (0.51–0.56)	0.40 (0.38–0.41)	<0.001
OFC, 1/Pa s	12.97 (12.00–13.94)	9.01 (7.14–10.88)	<0.001
$p_{\upsilon }$, mm Hg	51.15 (49.78–52.52)	54.07 (53.60–54.55)	<0.001

All values are expressed as median (interquartile range). P values were calculated with the Kruskal–Wallis rank test. Completers PAD group: n= 19; noncompleters PAD group: n=17. k ^t indicates transfer rate constant; K _tissue, interstitial permeability; OFC, outflow filtration coefficient; PAD, peripheral artery disease; $p_{\upsilon }$, microvascular pressure; and φ, porosity (values in the range from 0 to 1).
