Accessory Vertebral Artery: An Embryological Review With Translation from Adachi.
Review in Cureus, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
The vertebral arteries arise from the posterior superior aspect of the bilateral subclavian arteries and course superiorly through the transverse foramina of C1-C6 vertebrae before joining one another along the anterior surface of the pons. Developmental variations during the fourth to sixth weeks of embryonic development may result in the formation of accessory vertebral arteries, i.e., ipsilateral vertebral arteries of dual origin. This anatomical variation is distinct from and often confused with vertebral artery duplications and fenestrations. This article reviews the anatomy and embryology of the accessory vertebral artery with excerpts from Buntaro Adachi's classic text on vascular anatomical variations. Knowledge of accessory vertebral vessels is important during vascular and spinal procedures of the head and neck. Furthermore, these variations have been associated with cerebrovascular pathologies, such as stroke, dissection, and other hemodynamic anomalies.
