Does anticoagulation therapy improve outcomes in severe heart failure with reduced ejection fraction? A systematic review: Anticoagulation in severe heart failure: a systematic review.
Article in Annals of medicine and surgery (2012), 2025. 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: Heart failure with reduced ejection fraction (HFrEF) is a growing health concern, with an increased risk of thromboembolic events. Oral anticoagulants (OACs) are commonly used in HFrEF patients with atrial fibrillation, but their role in patients with sinus rhythm is unclear. Objective: To assess the safety and efficacy of OACs in HFrEF patients with sinus rhythm. Methods: A systematic review of seven studies involving 17 051 patients was conducted. Outcomes included mortality, nonfatal myocardial infarction (MI), nonfatal stroke, and hospitalization rates. Results: OACs significantly reduced non-fatal strokes compared to antiplatelets and placebo. A measurable reduction in nonfatal MIs was observed in most studies. However, no conclusive benefit was found regarding all-cause fatality and rehospitalization rates. The benefit of OACs in stroke prevention was counterbalanced by an increased risk of major bleeding episodes. Conclusion: OACs may have a role in reducing nonfatal cardiovascular events in HFrEF patients with sinus rhythm, particularly those with ischemic etiologies or underlying thrombotic states. However, further research is needed to establish their efficacy and safety in this population.
