Surgical Resection of a Metastatic Lung Tumor with Polypoid Extension Into the Left Atrium Using the Bilateral Transseptal Approach.
Article in Annals of thoracic surgery short 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
Lung tumor with polypoid extension into the left atrium (LA) poses a high systemic tumor embolism risk. We report a rare case of a woman with pulmonary metastasis from a retroperitoneal leiomyosarcoma extending into the LA as a polypoid mass through the left superior pulmonary vein. To minimize the risk of fatal embolization, complete resection was performed under cardiopulmonary bypass using a bilateral transseptal approach, enabling excellent visualization and precise intracardiac tumor resection before left upper lobectomy. She has remained recurrence free for 1 year. This approach safely manages lung tumors with polypoid LA invasion while mitigating catastrophic tumor embolism risk.
