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

backgroundNonvalvular atrial fibrillation (NVAF) patients with low CHA2DS2-VASc scores still have a risk of atrial thrombus formation. This study aims to identify these patients' risk factors for intracardiac thrombus or sludge.

methodsWe conducted a retrospective study of 919 consecutive hospitalized NVAF or atrial flutter patients with a CHA2DS2-Vas score ≤ 1 (male) and ≤ 2 (female) who underwent transesophageal echocardiogram (TEE) before catheter ablation at Beijing An Zhen Hospital from November 2016 to December 2017. We collected the clinical and echocardiographic characteristics of the patients.

resultsExcluding seven patients with hypertrophic cardiomyopathy, 919 patients, including 17 identified left atrial appendage (LAA) thrombus/sludge and 902 without LAA thrombus/sludge, were included. Among 17 patients with LAA thrombus/sludge, 16 (94.1%) had non-paroxysmal AF. A subgroup analysis was conducted in 403 non-paroxysmal atrial fibrillation (AF) patients. 87.8% had spontaneous echo contrast (SEC), 59.3% had severe or more severe SEC, and 4.0% had thrombus/sludge. In the multivariable model, female (odds ratio [OR] 4.612, 95% [CI] 1.454-14.627, p = 0.009) and LA diameter ≥ 45 mm (OR 13.340, [CI] 3.601, 49.415, p < 0.001) remained significantly independently associated with LAA thrombus/sludge.

conclusionAmong patients with NVAF and CHA2DS2-VASc scores ≤ 1 (male) and ≤ 2 (female), those non-paroxysmal AF patients who were female and had an LA ≥ 45 mm still had a risk of LAA thrombus/sludge formation.
