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

backgroundAtrial fibrillation (AF) is the most common arrhythmia and is associated with high morbidity and mortality, particularly in the aging population. Current treatment and prevention strategies remain suboptimal, highlighting the urgent need to better understand the mechanisms underlying aging-associated AF. We recently reported a causal role of the stress-activated kinase JNK2 (c-Jun N-terminal kinase 2) in aging-associated AF pathogenesis, mediated by JNK2-driven sarcoplasmic reticulum Ca

methodsWe used aged mice, intestinal epithelium-specific tight junction OD (occludin) knockdown (OD

resultsWe found that leaky gut significantly activates atrial JNK2, which, in turn, drives Ca

conclusionsActivated JNK2 functions as a pathological nodal integrator of leaky gut-associated stress signals, mediating gut-to-heart crosstalk and driving inflammation-induced AF pathogenesis. Targeting JNK2 may represent a novel therapeutic strategy for AF.
