Pooled, includes both patients with peripheral artery disease and controls. eGFR indicates estimated glomerular filtration rate; k ^t , transfer rate constant; K _tissue, interstitial permeability; Obs, number of observations; OFC, outflow filtration coefficient; PAD, peripheral artery disease; $p_{\upsilon }$, microvascular pressure; and φ, porosity.
