1 · What the graph read from it

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.

2 · The registry

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

Preoperative understanding of complex congenital heart disease is crucial for proper management. Surgical direction of partial anomalous pulmonary venous drainage and atrial septal defect closure when combined by the rare azygos continuation of interrupted inferior vena cava (IVC) may be associated with anomalous systemic to pulmonary venous connection, causing right-to-left shunt. We report a 44-year-old male with a history of congenital heart disease repaired in early childhood. Diagnostic imaging revealed an interrupted IVC with azygos continuation draining into the right upper pulmonary vein to the left atrium. CT plays an essential role in recognition of venous anomalies with unexplained cyanosis.
