Association Between Direct Oral Anticoagulant Score and Bleeding Events in Patients With Atrial Fibrillation Following Transcatheter Aortic Valve Replacement: A Retrospective Multicenter Cohort Study.
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 3 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
backgroundThe Direct Oral Anticoagulant (DOAC) Score can predict bleeding risk in patients with atrial fibrillation taking DOACs; however, it lacks external validation. Therefore, this study aimed to assess the association between the DOAC Score and bleeding events in patients with atrial fibrillation who underwent transcatheter aortic valve replacement. METHODS AND
resultsThis retrospective multicenter cohort study included patients with atrial fibrillation who underwent transcatheter aortic valve replacement, as registered in a Japanese multicenter registry. The primary end point was the incidence of bleeding. Patients were categorized based on their DOAC Score: low and moderate- (≤7 points), high- (8-9 points), and very high-risk (≥10 points) groups. Among 1230 patients (mean age 84.6±5.1 years; 457 men), 465 (37.8%) received a vitamin K antagonist, and the remaining patients received DOACs. The low and moderate-, high-, and very high-risk groups included 380 (30.1%), 497 (40.4%), and 353 patients (28.7%), respectively. The 3-year cumulative incidence of all bleeding events was significantly different among the 3 groups (low and moderate risk: 6.6%, high risk: 6.9%, and very high risk: 14.0%;
conclusionsThe DOAC Score was significantly associated with bleeding events in patients with atrial fibrillation after transcatheter aortic valve replacement, aiding in clinical decision-making for anticoagulant management.
