Analysis of risk factors for left atrial appendage thrombus formation in patients with atrial fibrillation.

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
objectiveTo identify predictors of left atrial appendage thrombus formation.
methodsWe retrospectively analyzed 149 patients with persistent or paroxysmal atrial fibrillation who underwent cardiovascular surgery between January 2015 and October 2023. Resected left atrial appendages were histologically evaluated for thrombus and amyloid deposition. After excluding 11 patients with transthyretin-type amyloids and 10 with rheumatic mitral valve stenosis, 128 patients (median age, 72.0 years; range, 37-84 years) were assessed. Patients were categorized into the thrombus and no-thrombus groups. Clinical data, echocardiographic findings, and atrial natriuretic peptide amyloid grades (0-3) were compared.
resultsFresh or organized thrombi and atrial natriuretic peptide amyloid deposition were observed in 28 (21.9%) and 110 (85.9%) patients, respectively. Moderate or greater aortic stenosis was more frequent in the thrombus group (p = 0.004). Although overall atrial natriuretic peptide amyloid deposition rates were similar (p = 0.377), amyloid deposition degree was significantly greater in the thrombus group (p < 0.001). Multivariate logistic regression identified moderate or greater aortic stenosis and amyloid deposition degree as independent predictors, whereas moderate or greater mitral regurgitation was a negative predictor.
conclusionsModerate or greater aortic stenosis and atrial natriuretic peptide amyloid deposition degree predicted left atrial appendage thrombus formation, whereas moderate or greater mitral regurgitation was a negative predictor.
