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

A rare vascular condition called persistent left superior vena cava (PLSVC) is frequently found incidentally when performing central venous catheterization (CVC). We report the case of a 57-year-old man, whose left-sided central line seemed to be incorrectly positioned on a chest X-ray with no associated anomalies; further imaging confirmed the presence of a PLSVC, which drained into the coronary sinus. It is important to recognize this variant in order to prevent diagnostic confusion and complications. PLSVC is typically asymptomatic, but PLSVC poses risks during invasive cardiac treatments. For safe clinical practice, it is crucial to be aware of this anatomical variation.
