Case report: Use of unenhanced cardiac MR to evaluate low flow states for thrombus.
Article in Radiology case reports, 2022. 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
Left atrial spontaneous echo contrast is an echocardiographic finding associated with hypercoagulable states and stasis and can be clinically correlated with a thromboembolism in patients with atrial fibrillation, mitral stenosis, or mitral valve repair. Black blood double inversion recovery cardiac magnetic resonance is used to map out cardiac anatomy and demonstrates higher signal in blood flowing at a slower rate, such as at the sites of aortic aneurysms, aortic dissections and vessel occlusions. Here, we present the case of a 66-year-old woman with persistent atrial fibrillation and left atrial findings of spontaneous echo contrast and high signal on black blood double inversion recovery cardiac magnetic resonance imaging, raising concern for a thrombus. However, this was ruled out with subsequent bright blood cardiac magnetic resonance imaging demonstrating high signal with transitory central swirling low signal in the left atrium. Thus, cardiac magnetic resonance imaging can be used to demonstrate non-thrombotic low flow states in cases where contrast is contraindicated.
