Anomalous origin of the left common carotid artery from the main pulmonary artery.
Article in BMJ case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
This case report highlights an exceptionally rare congenital anomaly where the left common carotid artery (LCCA) originates from the main pulmonary artery (MPA), a condition documented in only 12 cases globally. Typically, the LCCA arises from the aortic arch; however, in this situation, it attaches to the MPA, creating complications to cerebral blood flow. A patient in their first decade, with a history of symptomatic patent ductus arteriosus that required surgical closure shortly after birth due to persistent tachycardia and respiratory symptoms, presented to our clinic with recurrent headaches and chest infections lasting several months. To investigate these symptoms, a CT angiography was performed, revealing this rare vascular anomaly. Given the rarity of this condition and the patient's stable clinical status, conservative management was chosen. Continued monitoring remains essential to detect complications. More cases are needed to understand the outcomes and management strategies for this rare anomaly.
