Predicting reduced left atrial appendage velocity from echocardiographic left atrial function parameters in patients with atrial fibrillation undergoing catheter ablation.

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
Decreased left atrial appendage velocity (LAAV) is considered a significant risk factor thrombus formation in the left atrial appendage (LAA). The aim of this study was to assess the role of echocardiographic left atrial (LA) function parameters in predicting LAAV in patients with persistent atrial fibrillation (AF) undergoing catheter ablation. We prospectively enrolled consecutive patients with persistent AF undergoing transesophageal echocardiography (TEE) directly before the first AF ablation in 2019-2022. Of the 150 patients enrolled in the study, 29.3% (n = 44) had reduced LAAV values defined as < 25 cm/s. Patients with decreased LAAV values exhibited significantly reduced left atrial reservoir and conduit strain (LASr and LAScd), LA emptying fraction, and average e' values. This group also presented with a high LA stiffness index (LASI), high LA and right atrial area, and high LA volume index (LAVI) and E/e' ratio. In multivariable logistic regression analysis, LASI and LAVI remained significant predictors of the reduced LAAV. The threshold values were 1.6 for LASI and 44.47 ml/m
