Left Atrial Intimal Sarcoma Masquerading as Intracardiac Thrombus.
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 malignancies are rare and often present with non-specific clinical and imaging findings, leading to diagnostic delays. We report a case of a 76-year-old woman with progressive dyspnea who was found to have a left atrial mass initially suspected to be a thrombus or benign lesion because of the absence of significant uptake on fluorodeoxyglucose positron emission tomography (FDG-PET). However, progressive enlargement and infiltrative imaging features raised concern for malignancy. Histopathological evaluation ultimately confirmed undifferentiated pleomorphic sarcoma with MDM2 amplification, consistent with intimal sarcoma. This case highlights the limitations of FDG-PET in excluding cardiac malignancy and underscores the importance of integrating multimodal imaging with clinical suspicion to avoid diagnostic anchoring.
