No difference was identified in duration of vessel occlusion in limbs with deep venous insufficiency (DVI) compared with limbs without DVI (P = .117).

3. Fig 2
Box and whisker plots show that by fixed-effects modeling, the presence of deep venous insufficiency (DVI) had no effect on the rate of total venous clinical severity scores (VCSS) improvement (P = .572). The horizontal line in the middle of each box indicates the median; the top and bottom borders of the box mark the 75th and 25th percentiles, respectively. The whiskers mark the 90th and 10th percentiles.

4. Fig 3
Box and whisker plots show that by using fixed-effects modeling, there was significantly less improvement (P = .04) of venous clinical severity scores (VCSS) in limbs with complete vessel recanalization compared with vessels that remained occluded. The horizontal line in the middle of each box indicates the median; the top and bottom borders of the box mark the 75th and 25th percentiles, respectively. The whiskers mark the 90th and 10th percentiles.
