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

Background: Increased left ventricular extracellular volume (ECV) measured by cardiac magnetic resonance imaging is associated with myocardial damage and has been considered to predict atrial fibrillation (AF) recurrence after catheter ablation (CA). However, recent reports suggest that AF recurrence is infrequent even with high ECV owing to advancing ablation technology. Objective: This study aimed to evaluate the relationship between ECV quantified by computed tomography (CT-ECV), commonly performed before CA, and AF recurrence. Methods: Consecutive 467 patients undergoing their first CA for AF at our hospital between January 2021 and June 2023 received pre-CA contrast-enhanced CT. The relationship between CT-ECV and AF recurrence within 400 days after CA was examined. Results: AF recurrence occurred in 77 patients (16.5%), and CT-ECV in the nonrecurrence group was not significantly different from that in the recurrence group (28.0% vs 28.1%; Conclusion: CT-ECV was not significantly associated with AF recurrence within 400 days after the first CA. Regardless of the severity of ventricular myocardial damage, CA for AF is beneficial for preventing AF and improving cardiac function.
