*Based on # of limbs
† P-value for statistical comparison between baseline and 6 months was P < 0.0001
§ Bilateral subjects with clot in iliofemoral segments in only one leg were excluded in these two calculations since the outcomes may be impacted by the other leg with clot in isolated femoral-popliteal. Data from 371 subjects were included in these analyses
