Clinical and Genetic Risk Factors Predict Atrial Fibrillation on the Basis of Hypertrophic Cardiomyopathy.
Article in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundClinical and genetic predispositions are significant in predicting atrial fibrillation (AF); however, their role in patients with hypertrophic cardiomyopathy (HCM) remains unclear. This study aims to elucidate the impact of clinical and genetic risk factors on the development of AF in patients with and without HCM. METHODS AND
resultsThis retrospective analysis involved data from the UK Biobank cohort. Participants were divided into 3 groups based on their validated polygenic risk score for AF: the bottom 10% as low risk, the top 10% as high risk, and the rest as intermediate risk. We assessed the incidence of AF and cardiovascular complications and analyzed its predictors, including genetic risk. We examined 1180 patients with HCM (mean age, 61.1±7.1; 63.0% men) and 476 238 participants without HCM (mean age, 57.0±8.1; 45.3% men). During the 11.6-year follow-up period, the age- and sex-adjusted AF incidence rates for the low, intermediate, and high genetic risk groups were 2.4, 3.6, and 5.4 per 100 person-years in participants with HCM and 0.2, 0.5, and 1.0 per 100 person-years in participants without HCM, respectively. Genetic risk, evaluated as a continuous variable using polygenic risk score, was a less significant predictor of AF in the HCM group (hazard ratio [HR], 1.35 [95% CI, 1.21-1.49]) than in non-HCM group (HR, 1.57 [95% CI, 1.56-1.59];
conclusionsGenetic predisposition is associated with the development of AF and cardiovascular complications in people with and without HCM; this association was weaker in the HCM group.
