Double-Drainage Levoatrial Cardinal Vein: Cardiac CT Evaluation of Compensatory Pulmonary Venous Pathway in Univentricular Heart.
Article in JACC. Case reports, 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
case summaryAn 8-day-old boy with univentricular physiology presented with respiratory failure and persistent hypoxemia. Cardiac computed tomography angiography showed a dominant right ventricle with mitral atresia and an intact atrial septum, double-outlet right ventricle, and persistent ductus arteriosus. Pulmonary veins connected to the left atrium but were markedly dilated, with anomalous dual drainage through a levoatrial cardinal vein into the innominate and azygos veins. Despite emergent atrial septectomy, pulmonary artery banding, and ductal ligation, the outcome was unfavorable. TAKE-HOME MESSAGE: Distinguishing pulmonary venous connection from drainage is essential, and cardiac computed tomography angiography is key for surgical planning.
