Arcuate anterior jugular vein: a rare case report and its clinical relevance.

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
objectiveThe present study describes a rare anatomical variation of the anterior jugular vein (AJV) and discusses its clinical relevance.
methodsA head and neck specimen fixed in 10% formaldehyde from a 42-year-old female cadaver was submitted to angio technique with pre-vulcanized latex and water-soluble ink. During a routine dissection for the discipline of topographic anatomy, the presence of an arcuate AJV was detected in the anterior triangle of the neck.
resultsAn arcuate AJV was formed by the confluence of the submental and facial veins in the left submandibular region, which presented a complex network of anastomoses superficially to the left submandibular gland. After its origin, this vessel curved to the right at the level of the laryngeal prominence and followed the medial border of the right sternohyoid muscle to flow into the right AJV. In this topography, the arcuate AJV was located between the sternocleidomastoid muscle's anterior margin and the thyroid gland's right lobe. The presence of anastomoses between the two AJVs communicating the submandibular triangles was not detected.
conclusionThe arcuate AJV is a relevant anatomical variant in the superficial venous drainage of the neck that should be known by head and neck surgeons and radiologists to avoid surgical iatrogenic events.
