Aberrant Right Subclavian Artery: A Case Report.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
During routine dissection of a medical cadaver, an aberrant right subclavian artery (ARSA) was identified originating from the aortic arch. An ARSA, present in 0.2-2.5% of the population and often asymptomatic, increases the risk of surgical nerve injury during head, neck, and thoracic surgeries. ARSAs can also impinge on the esophagus and cause dysphagia or odynophagia, impinge on the trachea and cause dyspnea, or be impinged by the esophagus and/or trachea, limiting blood supply to the upper extremity. Most often, ARSAs follow a retroesophageal course, as in this case. In addition to the ARSA, the vertebral arteries were also variant and branched directly off the common carotid arteries, as opposed to the subclavian arteries, and the right recurrent laryngeal nerve was nonrecurrent. This case describes a donor with three anatomical anomalies to highlight the clinical relevance of recognizing ARSA and related variants and how to identify signs and symptoms of a symptomatic ARSA.
