Anomalous Origin of the Left Coronary Artery From the Right Pulmonary Artery (ALCARPA): A Case Report.
Article in Cureus, 2025. 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
Although the congenitally anomalous left coronary artery (LCA) is a rare condition, it can give rise to a most rare case, which is an anomalous LCA from the right pulmonary artery (RPA) (ALCARPA). If left untreated, ALCARPA results in myocardial territories receiving low-pressure, oxygen-poor blood. A male infant aged eight months exhibited signs of respiratory distress, poor feeding, and precordial activity. The diagnosis of ALCARPA is usually considered in infants with otherwise unexplained left ventricular dysfunction or mitral valve regurgitation. Imaging studies, including computed tomography angiography and echocardiography, showed a markedly dilated right coronary artery and a dilated left ventricle, confirming ALCARPA. Using autologous pericardium treated with glutaraldehyde, the abnormal LCA was directly anastomosed to the aorta. Postoperative recovery was uneventful, with elective inotropic support provided. To prevent fatal arrhythmias and myocardial ischemia, prompt diagnosis and surgical creation of a dual-coronary system are essential.
