Uterine artery projection relative to anatomical bony landmarks in CT-angiographies.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe aim was to find bony landmarks of the pelvis for the origins and routes of uterine arteries, hoping to improve speed and safety of embolization procedures (leiomyoma, post-partum bleedings…).
methodsWe carried out a study based on the analysis of CT-angiographies in arterial phases of whole-body scans. Two measurements were done per artery, one from the origin of uterine arteries to a first perpendicular line passing through the lowest part of the sacroiliac joint, another one from the beginning of the parametrial segment from a second parallel line passing by the acetabular roof. Mean distances across all these measurements were calculated, as were potential associations with known variables such as anatomical variants, age, parity and any pelvic surgical history.
resultsTwo hundred uterine arteries were analyzed. Concerning the origin, 83.5% of uterine arteries were located approximately one centimeter around the first line defined above, with a mean distance of + 4.8 mm. Concerning parametrial segment beginning, 88% were located approximately one centimeter around the second line defined, with a mean distance of only + 3.9 mm above the acetabular roof. Some significant differences were observed in subgroups, notably with a small trend to higher arising of uterine arteries in patients who had at least one childbirth, and expectedly lower arising in distal anatomical variants.
conclusionClear pelvic anatomic landmarks exist and could help the guidance of arteries catheterization, and therefore indirectly lead to faster embolization and optimize procedures safety.
