Genetic Determinants of Left Atrial Function Are Associated With Stroke.
Article in Journal of the American Heart Association, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
backgroundWhile atrial fibrillation (AF) is a key risk factor for stroke, recent studies have suggested that atrial cardiomyopathy may also increase stroke risk in the absence of AF. This study aimed to evaluate genetic determinants for left atrial (LA) function and volumes and risk of stroke. METHODS AND
resultsPolygenic scores (PGSs) for LA measures were constructed and used in 380 017 individuals in the UK Biobank, without history of ischemic stroke, systemic arterial embolism, or AF at enrollment. Risk of ischemic stroke was estimated using time-to-event models, considering all-cause death and incident AF as competing events. Systemic arterial embolism was investigated as a secondary end point. The PGS for LA passive emptying fraction was associated with risk of ischemic stroke. Individuals with a PGS for LA passive emptying fraction in the lowest quartile had a hazard ratio (HR) of 1.12 for ischemic stroke compared with those in the top quartile (
conclusionsThe PGS for LA passive emptying fraction was significantly associated with incident ischemic stroke when considering AF as a competing risk. Consistent results were found in Mendelian randomization analyses. These findings suggest that atrial dysfunction may influence stroke risk independently of AF.
