IgG4-Related Aortitis Masking as Intramural Hematoma on Imaging.
Article in JACC. Case reports, 2026. 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
backgroundIgG4-related aortitis is a rare fibroinflammatory disease characterized by thoracic or abdominal aortic wall thickening and dilation. CASE SUMMARY: A 24-year-old man presented after blunt trauma and was found to have intramural hematoma in the ascending aorta on chest computed tomography. Given the high-impact injury, aortic injury could not be excluded. Therefore, he underwent a hemiarch replacement; intraoperative findings and histopathology were concerning for IgG4-related aortitis. DISCUSSION: IgG4 aortitis of the ascending aorta is rare, with only a few case reports in the literature. On computed tomography, IgG4 aortitis can mimic acute aortic syndrome, which poses a challenge regarding appropriate management. TAKE-HOME MESSAGES: IgG4 aortitis can mimic acute aortic syndrome findings on imaging. This poses a clinical dilemma in the management of these patients, and surgical intervention should only be offered in the appropriate clinical scenario.
