Subjective examination quality
CIA
SECONDARY
SEQ (secondary outcome) was independently rated by two vascular interventional radiologists. SEQ was rated in the AA, CIA, SFA, PA, and calf arteries. In the case of the three calf arteries, the artery with the best demarcation of the lumen was rated. In cases of occlusion, SEQ was not assessed at that anatomical level.A 4-point rating scale was used, as follows: 1: Excellent, 2: good, 3: adequate, 4: non-diagnostic, where ratings 1 through 3 were considered diagnostic quality (Fig. Likert scale for subjective examination qualityDisagreements on whether SEQ was non-diagnostic were resolved by a referee, a third vascular interventional radiologist. The resolved rating was the median of the three ratings.
