Rupture of a mediastinal collateral aneurysm associated with unilateral absence of pulmonary artery.
Article in Journal of vascular surgery cases and innovative techniques, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Isolated unilateral absence of pulmonary artery is a rare congenital malformation and often asymptomatic in adults. However, aneurysm formation in the aortopulmonary collateral vessels carries a potential risk of life-threatening hemorrhage. This case report describes a 79-year-old woman who presented with rupture of a mediastinal collateral aneurysm associated with isolated unilateral absence of pulmonary artery. We discuss the clinical course, including vascular morphology changes, and subsequent endovascular treatment. Notably, this case demonstrates the rupture of a de novo collateral aneurysm rather than a preexisting one.
