Associations of Integrated Left Ventricular Myocardial Strain Metrics and Incident 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
Background: Data on associations between left ventricular (LV) strain metrics and incident atrial fibrillation (AF) remains limited, particularly regarding integrated effects of multi-directional strains. This study aimed to investigate the associations of LV global longitudinal strain (GLS), radial strain (GRS) and circumferential strain (GCS) measured by cardiac magnetic resonance with incident AF. Methods: This prospective cohort study included 36,876 AF-free UK Biobank participants (52.5% female; median age 64.0 years). Incident AF was ascertained via ICD-10 codes. Impaired strain metrics were defined as the absolute value of lower 5%. Cox proportional hazards regression (adjusting for demographic characteristics, lifestyle factors, cardiac imaging indices, and clinical features) was performed to assess the associations of LV strain metrics and incident AF. Results: Over 6.88 ± 1.63 years, 862 incident AF events occurred. GLS (HR 1.22, 95%CI 1.13-1.31), GRS (0.88, 0.80-0.96), and GCS (1.27, 1.15-1.40) were independently associated with AF (all Conclusion: LV GLS, GRS, and GCS are linked to incident AF. Combined strain impairment improves AF risk stratification, especially in adults ≥ 60 years.
