Racial and Ethnic Disparities in the Use and Outcomes With WATCHMAN FLX: A SURPASS Analysis of the NCDR Left Atrial Appendage Occlusion Registry.

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
backgroundLeft atrial appendage occlusion (LAAO) is increasingly used as an alternative to oral anticoagulation for stroke prevention in select patients with atrial fibrillation. Data on outcomes in racial and ethnic minority individuals are limited. This analysis assessed differences in the use and outcomes of LAAO by race and ethnicity in a large national registry. METHODS AND
resultsThis analysis acquired data on patients who underwent WATCHMAN FLX implantation from the retrospective NCDR (National Cardiovascular Data Registry) LAAO registry through September 2022. All patients with an attempted WATCHMAN FLX implantation and known race and ethnicity were included. Baseline characteristics and 1-year event rates were compared. A total of 97 185 patients were analyzed; 87 339 were White individuals (90%), 3750 Black individuals (3.9%), and 2866 Hispanic individuals (Hispanic/Latinx), 2.9%). Black and Hispanic patients were younger, with a higher incidence of prior stroke and significant bleeding compared with White patients. Black and Hispanic patients were treated with LAAO in smaller numbers relative to their proportion of the US population. Rates of procedural success were similar between groups. Though direct oral anticoagulants were prescribed in most patients across the groups, dual and single antiplatelet therapy were prescribed more often in Black patients. Black patients had significantly higher rates of 1-year death and bleeding compared with White and Hispanic patients.
conclusionsPatients from racial and ethnic minority groups comprise a disproportionately small fraction of all patients who undergo LAAO. Black and Hispanic patients were younger but had significantly higher comorbidities compared with White patients. Procedural success was similar among the groups, but Black patients experienced higher rates of death and bleeding at 1 year.
