Efficacy and safety of direct oral anticoagulants for intermediate stroke risk in patients with atrial fibrillation (SINGLE-AF): Study design and protocol.
Article in Heart rhythm O2, 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
Background: The optimal antithrombotic strategy for patients with atrial fibrillation (AF) with intermediate stroke risk (CHA Objective: This study aimed to conduct a randomized clinical trial evaluating the safety and efficacy of OAC therapy compared with no OAC therapy in patients with AF at intermediate stroke risk. Methods: The Efficacy and Safety of Nonvitamin K Antagonist Oral Anticoagulants for Intermediate Stroke Risk in Patients With Atrial Fibrillation trial is an investigator-initiated, multicenter, open-label, superiority, randomized trial with blinded outcome assessment, enrolling 1800 patients with AF who have 1 nongender stroke risk factor, as indicated by their CHA Results: The primary endpoint is a composite of stroke, systemic embolism, major bleeding as defined by the International Society on Thrombosis and Hemostasis criteria, and cardiovascular death, assessed at 2 years after randomization. We hypothesized that OAC therapy would be superior to no OAC therapy for the net composite outcome among patients with AF. Conclusion: The Efficacy and Safety of Nonvitamin K Antagonist Oral Anticoagulants for Intermediate Stroke Risk in Patients With Atrial Fibrillation trial will evaluate the efficacy and safety of OAC therapy vs no OAC in patients with AF with a single nongender stroke risk factor, aiming to provide evidence to guide anticoagulation strategies in those with intermediate stroke risk.
