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: The optimal voltage threshold for determining low voltage areas (LVA) in non-paroxysmal atrial fibrillation ( Methods: Bipolar LA and LAA voltage in 40 NPAF and 42 patients with no AF (control group) were studied in sinus rhythm (SR) and AF (NPAF group) and SR only in the control group. Bipolar LA and LAA voltage distribution were compared between the NPAF and control groups. Fibrotic regions identified by late gadolinium-enhanced magnetic resonance imaging (LGE-MRI) was used as the reference standard comparison in the NPAF group. Results: The median, 5th percentile (V Conclusion: A patient-tailored low voltage threshold can be obtained using a simplified equation and provides more accurate representation of LVA in NPAF than universal thresholds.
