Predictors for reduced flow velocity in left atrial appendage during sinus rhythm in patients with atrial fibrillation.
Article in Heart and vessels, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
Discontinuation of anticoagulation therapy after catheter ablation (CA) for atrial fibrillation (AF) remains controversial. While decreased left atrial appendage flow velocity (LAAFV) during AF leads to left atrial appendage thrombus and embolic events, some AF patients show decreased LAAFV even during sinus rhythm (SR). We studied 392 patients (256 males, 68 ± 10 years) who exhibited SR during transesophageal echocardiography (TEE) before CA for AF. Clinical factors, transthoracic echocardiography, and blood samples were obtained before TEE. Reduced LAAFV was defined as < 35 cm/s of LAAFV. Reduced LAAFV was observed in 72/392 patients (18%). Reduced LAAFV was significantly associated with high prevalence of non-paroxysmal AF, elevated brain natriuretic peptide (BNP), prior heart failure, high CHADS
