Relationship of blood flow in lower abdomen to the three arteries. BFAb was more strongly related to BFAo (r = 0.966, p < 0.0001) than to BFLFA or BFRFA (r = 0.303, p = 0.0327 in LFA; r = 0.281, p = 0.0482 in RFA) (n = 50). Ao, abdominal aorta; LFA, left femoral artery; RFA, right femoral artery; Ab, lower abdomen. Blood flow in the Ao, LFA, RFA and Ab is defined as BFAo, BFLFA, BFRFA, and BFAb respectively.
