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

Persistent left superior vena cava (PLSVC) is the most common congenital thoracic venous anomaly and is usually clinically silent. We report a critically ill patient in whom PLSVC was identified after left internal jugular central venous catheter placement. Chest radiography showed a vertically oriented catheter along the left mediastinum without expected midline crossover, raising concern for malposition. Review of prior imaging confirmed PLSVC draining into the coronary sinus. Recognition of this variant prevented unnecessary catheter removal and repeat instrumentation, underscoring the importance of correlating procedural findings with imaging during left-sided venous access.
