Association Between Bradyarrhythmia Requiring Permanent Pacemaker Implantation and Epicardial Adipose Tissue in Elderly Patients.
Article in Journal of arrhythmia, 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: Aging is one of the most significant risk factors for sinus node (SN) and atrioventricular node (AVN) dysfunction. Epicardial adipose tissue (EAT) is reported to promote myocardial fibrosis and influence intracardiac conduction through the release of inflammatory cytokines and direct tissue infiltration. The SN and AVN are in contact with EAT, which may affect the SN function and AVN conduction. The purpose of this study was to examine the association between bradyarrhythmia and EAT. Methods: We enrolled 103 patients with bradyarrhythmia requiring permanent pacemaker (PM) implantations and 105 patients who underwent catheter ablation of paroxysmal supraventricular tachycardia in our hospital as a control (all patients were over 65 years old) and analyzed the preoperative echocardiograms retrospectively and measured the EAT thickness. We compared the EAT thickness between the PM group and control. Results: There were 38 (36.9%) PM group patients with sick sinus syndrome and 65 (63.1%) with advanced atrioventricular block. The EAT was significantly thicker in the PM group than control (PM group 4.6 ± 1.2 mm vs. control 3.6 ± 1.3 mm, Conclusions: The EAT thickness was associated with bradyarrhythmia requiring permanent PM implantation and may become a risk factor for SN and AVN dysfunction in elderly people.
