Left atrial wall shear stress correlates with fibrosis in patients with atrial fibrillation.
Observational study in Nature cardiovascular research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Left atrial wall fibrosis has an important role in atrial fibrillation (AF) because of the abnormal electrophysiological properties of the fibrotic areas. However, the mechanisms behind the development of left atrial fibrosis are not well understood. Here, we examine the association between regional wall shear stress and areas with fibrosis in the left atrium of patients with AF. We recruited 15 patients with AF for an observational prospective study involving baseline three-dimensional (3D) electroanatomical mapping of the left atrium and preinterventional cardiovascular magnetic resonance imaging to detect left atrial fibrosis. We extracted a 3D anatomical model of the left atrium from the electroanatomical maps. Then, we calculated regional time-averaged wall shear stress (TAWSS) and blood stagnation by performing patient-specific computational fluid dynamic simulations. We found that fibrosis and electrical scarring were more prevalent in areas exposed to high TAWSS without blood stagnation, whereas areas with low TAWSS were associated with blood stagnation.
