Table 2.
Superficial femoral artery (SFA) hemodynamic responses at baseline and post-intervention (< 10 min). Dbase, baseline diameter; SR, shear rate; Dpeak, peak diameter; Ddiff, change in diameter; FMD, flow-mediated dilation. Data are mean ± SD for baseline and post values, except for adjusted FMD, which are mean ± SE. Change scores are mean ± SE.
