A Case of Chronic Expanding Pericardial Hematoma Treated Surgically.
Article in Cureus, 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
Chronic expanding hematoma (CEH) is a rare condition characterized by a slowly enlarging hematoma. While chronic expanding hematomas can occur following trauma or surgery, their idiopathic presentation is exceedingly rare. An expanding hematoma can silently lead to diastolic cardiac dysfunction. A 69-year-old woman without a history of thoracic surgery or chest trauma presented with an incidentally discovered pericardial mass measuring 90 × 60 × 45 mm. Imaging revealed a mass with a calcified capsule that compressed the right heart in the anterior mediastinum. Despite initial attempts at off-pump resection, the procedure was converted to on-pump resection because of cardiac injury caused by extensive adhesions. The excised specimen was encapsulated and filled with an old hematoma. Histopathological examination results confirmed the diagnosis of chronic expanding hematoma with no evidence of malignancy. Despite being asymptomatic, the mass was significantly compressing the heart, necessitating surgical resection for diagnostic and therapeutic purposes.
