Chronic cyanosis since infancy: Unveiling a giant right pulmonary arteriovenous malformation.
Article in Radiology case reports, 2025. 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
Giant pulmonary arteriovenous malformations (PAVMs) are rare vascular anomalies involving direct connections between pulmonary arteries and veins, leading to right-to-left shunting and systemic hypoxemia. While small PAVMs may be asymptomatic, larger lesions often present with dyspnea, cyanosis, and related complications. An 18-year-old female with progressive dyspnea and cyanosis-first noted during infancy-was found to have a giant PAVM in the right lower lung lobe on thoracic computed tomography (CT). Imaging, particularly computed tomography (CT), was essential for diagnosis and treatment planning. This case underscores the need to consider PAVMs in the differential diagnosis of chronic cyanosis and highlights the critical role of radiologists in identifying and characterizing these lesions to guide appropriate management.and characterizing these lesions to support optimal clinical decision-making.
