Tuberculosis Effusive-Constrictive Pericarditis.
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
backgroundEffusive-constrictive pericarditis is a rare pericardial syndrome characterized by the coexistence of constrictive physiology and pericardial effusion. Tuberculosis remains a leading cause of pericardial disease in endemic regions, posing significant diagnostic challenges. CASE SUMMARY: A 67-year-old man from Brazil presented with progressive dyspnea, low-grade fever, and signs of right-sided heart failure. Imaging demonstrated constrictive physiology and progressive pericardial calcification. He developed cardiac tamponade requiring surgical pericardiectomy. Analysis of the pericardial fluid revealed a purulent effusion with elevated adenosine deaminase levels (200 U/L), consistent with tuberculous etiology. Despite medical and surgical management, the patient deteriorated owing to refractory shock. DISCUSSION: This case illustrates the complex interplay between effusion and pericardial constriction and underscores the diagnostic utility of imaging and biochemical markers such as adenosine deaminase in tuberculosis-endemic settings. TAKE-HOME MESSAGES: Tuberculosis remains a leading cause of effusive-constrictive pericarditis in endemic regions. Early recognition is critical to guide timely and appropriate therapy.
