Group	Day +1 (% mean ± SD)^*^†	Day +7 (% mean ± SD)^*^†	Day +15 (% mean ± SD)^*^†	P
Femoral	33.29 ± 10.57	50.05 ± 11.58	73.23 ± 15.52	<0.01
	(21.88–47.82)	(40.79–69.97)	(47.49–86.75)
Iliac	22.13 ± 9.93	39.87 ± 12.90	51.86 ± 11.35	<0.01

↵* Data are expressed as mean ± SD (range).
↵† Mean, SD, and ranges of percentage of perfusion of treated leg compared with contralateral leg.
P = comparison between ¹³N-ammonia uptake on day +1 vs. day +7, day +1 vs. day +15, and day +7 vs. day +15 for I group and F group.
