Challenges in neonatal ductal stenting: When to avoid tortuous ducts and pulmonary artery stenosis.
Article in Annals of pediatric cardiology. 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
Ductal stenting (DS) is the preferred palliative approach to the Blalock-Thomas-Taussig shunt (BTTS) for neonates with duct-dependent pulmonary circulation. However, appropriate case selection remains a critical challenge. This report explores the limitations of DS through illustrative examples and defines the subset in which neonatal DS is better avoided. Tortuous ducts increase the risk of procedural failure, ductal spasm, and pulmonary artery (PA) jailing. These can generally be managed with wire techniques and stiff wires. If extreme curvature persists despite these measures, it is best to abandon the procedure. Bilateral PA stenosis needs careful strategic planning and is often better managed surgically. Procedural risk is significantly high when both branch PA stenosis and tortuosity coexist, necessitating a BTTS. This pictorial report specifies anatomical substrates that are unsuitable for neonatal DS to improve safety and efficacy. It is intended as a visual reference for interventionists facing comparable clinical scenarios, particularly in early career.
