1 · What the graph read from 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.

2 · The registry

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

Anticoagulant therapy plays a pivotal role in preventing stroke and thromboembolic complications in elderly patients with atrial fibrillation, a population at increased risk for both ischemic and bleeding events. This systematic review evaluates the comparative efficacy and safety of direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs) in elderly patients with nonvalvular atrial fibrillation. A comprehensive literature search was conducted across PubMed, Embase, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL), following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and included only English-language randomized controlled trials (RCTs) focusing on patients aged 70 years or older. Five high-quality RCTs met the eligibility criteria. The findings consistently support the non-inferiority or superiority of DOACs compared to warfarin in preventing stroke, with a significantly lower risk of intracranial hemorrhage. However, a higher incidence of extracranial bleeding, particularly gastrointestinal bleeding, was observed with certain DOACs, especially at higher doses in patients aged 80 years and older. The review also highlights a possible role of anticoagulation in cognitive protection, although current evidence is limited. Overall, DOACs appear to be an effective and generally safer alternative to VKAs in elderly patients, but individualized treatment decisions remain essential, particularly in those with advanced age, renal impairment, or elevated bleeding risk.
