Correlation between myocardial radiomics features at the left atrium-left atrial appendage junction and stroke risk in atrial fibrillation patients: a retrospective case-control study.

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
Objective: This study aimed to systematically evaluate the microstructure changes of the myocardium at the left atrium-left atrial appendage (LA-LAA) junction in patients with atrial fibrillation (AF)-related cardioembolic stroke, and to explore its potential role as an imaging marker associated with stroke. Methods: This retrospective study included four groups: AF-related cardioembolic stroke group ( Results: Compared with AF patients without stroke, patients with AF-related cardioembolic stroke significantly increased myocardial thickness at the LA-LAA junction [7.1 (6.43-8.33) mm vs. 6.58 ± 1.45 mm, Conclusion: Both myocardial radiomics features and myocardial thickness at the LA-LAA junction may serve as potential imaging markers associated with AF-related cardioembolic stroke. Their incremental value for stroke risk stratification beyond established clinical risk factors requires further validation in larger prospective cohorts.
