Coronary artery fistulas as a rare cause of heart failure and ventricular arrhythmia, associated with multiple large vessel fistulas.
Article in Radiology case reports, 2023. 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
Coronary artery fistulas are abnormal connections between the coronary arteries with a heart chamber or any of the major blood vessels. Fistulous connections between systemic arteries and pulmonary vessels are even less frequent. We present a case of a 71-year-old man with symptoms of dyspnea, exercise intolerance, and ventricular arrhythmia who attended the emergency department. Coronary angiography revealed bilateral coronary fistulas drained into the pulmonary circulation. Computed tomography angiography revealed the presence of fistulas arising from the descending aorta, right internal mammary artery, and subclavian arteries, all these drained into the pulmonary circulation. Due to the rarity of the disease, there are no international guidelines for the management of coronary fistulas and the treatment is controversial. Coronary artery fistula is a rare pathology that should be included in the differential diagnosis of heart failure and ventricular arrhythmia.
