Comparison of non-vitamin K antagonist oral anticoagulants and well-controlled warfarin in octogenarians with non-valvular atrial fibrillation: Real-world data from a single tertiary center.

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
objectiveAtrial fibrillation (AF) is the most common arrhythmia in clinical practice, and its prevalence increases with age. Nevertheless, data about the use of oral anticoagulants (OACs) among patients with ≥80 years remains limited. This study aimed to evaluate the efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOACs) and warfarin in octogenarians with non-valvular AF (NVAF).
methodsMedical records of 387 patients who were ≥80 years and diagnosed with NVAF in our hospital between January 2017 and December 2019 were evaluated retrospectively. Patients with NVAF were divided into 2 groups (NOACs and warfarin), and the incidence of stroke/systemic embolism and major bleeding were analyzed.
resultsA total of 322 patients were included in the study. The median follow-up duration was 10.9 months for the NOACs group and 12.1 months for the warfarin group. The primary efficacy outcome was stroke/systemic embolism, and the primary safety outcome was major bleeding. A total of 220 patients were taking NOACs, and the most preferred NOACs were apixaban (53.6%), rivaroxaban (29.5%), dabigatran (13.2%), and edoxaban (3.6%) in this order. During a mean follow-up of 302.7 patient-years, the incidence of stroke or systemic embolic events was slightly higher among patients with warfarin but the difference was not statistically significant (p=0.862). The incidence rates of major bleeding events were similar between the treatment groups (p=0.824).
conclusionOur study revealed that the safety and efficacy outcomes are similar between the 2 treatment groups in octogenarians with NVAF.
