Rapid Embolic Event Chain: An Unusual Presentation of Marantic Endocarditis.
Article in Cureus, 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
Nonbacterial thrombotic endocarditis (NBTE), formerly known as marantic endocarditis, is characterized by sterile, noninfectious vegetations typically associated with hypercoagulable states, most commonly malignancies. Despite its noninfectious nature, NBTE can lead to serious complications similar to those seen in infectious endocarditis, including stroke, venous thromboembolism, splenic or hepatic infarcts, and acute intestinal ischemia. We present an unusual case involving a cascade of rapid embolic events in a patient newly diagnosed with metastatic lung cancer. The patient developed critical limb ischemia requiring bilateral below-knee amputation, with an echocardiogram revealing mitral valve vegetations. Postoperatively, the patient suffered an acute stroke and acute coronary syndrome, ultimately resulting in death. This case underscores the importance of early recognition and intervention in NBTE to prevent severe thromboembolic complications.
