Malposition of a Port Catheter in the Azygos Vein: Endovascular Repositioning Using a Long Loop Snare Technique.

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
Port catheters provide a reliable, long-term venous access option in children for repeated administration of medications or parenteral nutrition. A cardiac catheterization procedure was performed in a 7-year-old girl in whom lateral chest radiography revealed posterior deviation suggestive of azygos vein malposition. To avoid surgical replacement, a long loop snare technique was employed to safely withdraw the catheter into the superior vena cava with restoration of catheter function. This case highlights that endovascular long loop snare repositioning offers a feasible, minimally invasive alternative to surgical intervention for rare port catheter malpositions in pediatric patients.
