Double Trouble in the Pericardium: A Rare Co-Infection of Tuberculosis and Tularemia Leading to Cardiac Tamponade.
Article in Journal of medical cases, 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
Cardiac tamponade attributed to co-infection with multiple pathogens is rare. A 40-year-old man who migrated from India 10 years prior with no medical history presented with a progressive dyspnea, night sweats, intermittent fevers, weight loss over a 3-month period, and a cough. An echocardiogram revealed cardiac tamponade and further biopsy revealed necrotizing granulomas with diffuse necrotic lymphadenopathy. Early anchoring bias led to an extensive tuberculosis (TB) workup which was initially negative. However, after broadening the differential, a co-infection of tularemia and latent extrapulmonary TB was identified as the etiology of cardiac tamponade. While tularemia in the setting of immunodepression has been identified as a cause for pericarditis, there is no current literature of a tularemia and TB co-infection causing cardiac tamponade. This case highlights the importance of expanding a differential diagnosis when the presentation does not fit the diagnosis, especially when a delay in management can be consequential.
