Nonbacterial Thrombotic Endocarditis of a Mitral Prosthesis After Warfarin, Enoxaparin, and Apixaban Failure.

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) is an uncommon condition that carries significant morbidity and an in-hospital mortality rate of up to 36%. Involvement of a prosthetic valve with NBTE is even more rare. We present a case of prosthetic mitral valve NBTE that manifested 5 months after surgical mitral valve replacement. The patient's presentation was complicated by complex medical comorbidities and previous contraindications to multiple anticoagulant agents that included calciphylaxis secondary to warfarin and high concern for heparin-induced thrombocytopenia. The patient was taking apixaban when she developed prosthetic valve NTBE. The patient was transitioned to fondaparinux, with resolution of the mitral valve vegetations. Warfarin and heparin are first-line anticoagulant agents for antiphospholipid syndrome and NBTE, respectively. There is limited evidence for different anticoagulant agents in NBTE. Our case highlights nuance in the diagnosis of NBTE and complexities of anticoagulation decisions in patients with contraindications to various agents.
