Right Atrial Angiosarcoma Presenting With Cardiac Tamponade, Hemorrhagic Pericardial Effusion, and Pulmonary Embolism: A Case Report.
Article in Cureus, 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
Primary cardiac angiosarcoma is a rare and aggressive malignancy most commonly arising from the right atrium. We report a 43-year-old male patient who had no known comorbidities and was not receiving any regular medications. He presented with abdominal and epigastric pain and was found to have severe pericardial effusion, cardiac tamponade, a large right atrial mass, hemorrhagic pericardial effusion, and bilateral pulmonary emboli. He underwent urgent pericardiocentesis followed by open-heart surgery for excision of the right atrial mass, pericardial window creation, and mediastinal lymph node biopsy. Histopathology confirmed angiosarcoma infiltrating the right atrium, pericardium, and associated thrombus. Postoperative recovery was uneventful, and oncology recommended systemic chemotherapy. This case highlights atypical presentations of cardiac angiosarcoma and outlines the surgical and diagnostic approach.
