Association between atrial fibrillation and gastrointestinal bleeding: pathophysiology, risk stratification, and management - a narrative review.
Review in Annals of medicine and surgery (2012), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, significantly increasing the risk of thromboembolic events, necessitating anticoagulation therapy. However, anticoagulation, particularly with novel oral anticoagulants, elevates the risk of gastrointestinal bleeding (GIB), creating a clinical dilemma in managing AF patients. This narrative review explores the pathophysiology linking AF and GIB, emphasizing the hypercoagulable state in AF and the mucosal damage caused by anticoagulants. Epidemiological data reveal that GIB incidence in AF patients ranges from 1.32% to 5.4% annually, with risk factors including older age, prior GIB, and concomitant antiplatelet use.
