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
Background: Major aorto-pulmonary collateral arteries are congenital remnants of the segmental arteries that supply the lungs. They are commonly associated with congenital heart disease, particularly in cases where the main pulmonary artery branches are not well developed, these segmental collaterals do not regress and continue to supply oxygenated blood to the pulmonary vasculature. Over time, these collaterals can become problematic, particularly if they enlarge, leading to clinically significant symptoms such as haemoptysis, segmental pulmonary hypertension, and left heart volume overload. Case summary: Herein, we describe a rare case of isolated major aorto-pulmonary collaterals without associated congenital heart disease that presented with haemoptysis and managed percutaneously with a modified flow-reducer device. Discussion: This is a novel therapy for this very unique clinical scenario. Both multidisciplinary discussion and patient centred shared decision-making were utilized while discussing this case.
