Right Atrial and SVC Cardiac Sarcoidosis: Not All Atrial Masses Are Tumors.
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
backgroundRight atrial (RA) masses create diagnostic challenges; extension into surrounding venous structures is rare. CASE SUMMARY: A 56-year-old woman presented with variable heart block and was found to have an RA mass extending into the superior vena cava (SVC). DISCUSSION: RA involvement in sarcoidosis is rare, and SVC extension has not been reported. This case highlights the diagnostic challenges associated with this presentation and the importance of a multidisciplinary approach. TAKE-HOME MESSAGES: Cardiac sarcoidosis may present as a rapidly developing RA mass with rare venous extension, complicating therapeutic options. Multidisciplinary evaluation and management are necessary for treatment.
