Racial/ethnic and sex differences in safety outcomes and atrial fibrillation/atrial flutter-related acute healthcare utilization after catheter ablation of atrial fibrillation.

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
Background: Catheter ablation is recommended for the treatment of symptomatic atrial fibrillation (AF) refractory to medical therapy. Objective: The study sought to examine racial/ethnic and sex differences in complications and AF/atrial flutter (AFL)-related acute healthcare utilization following catheter ablation for AF. Methods: We performed a retrospective analysis using data from the Centers for Medicare and Medicaid Services Medicare Standard Analytical Files (October 1, 2014, to September 30, 2019) among patients ≥65 years of age with AF who underwent catheter ablation for rhythm control. The risk of any complication within 30 days and AF/AFL-related acute healthcare utilization within 1 year of ablation by race, ethnicity, and sex were assessed using multivariable Cox regression modeling. Results: We identified 95,394 patients for analysis of postablation complications and 68,408 patients for analysis of AF/AFL-related acute healthcare utilization. Both cohorts were ∼95% White and 52% male. Female patients had a slightly elevated risk of complications compared with male patients (adjusted hazard ratio [aHR] 1.07, 95% confidence interval [CI] 1.03-1.12). Black (aHR 0.78, 95% CI 0.77-1.00) and Asian (aHR 0.67, 95% CI 0.50-0.89) patients had lower utilization compared with White patients. Specifically, Asian men (aHR 0.58, 95% CI 0.38-0.91) had lower utilization compared with White men. Conclusion: Differences in safety and healthcare utilization after catheter ablation for AF were observed by race/ethnicity and sex groups. Underrepresented racial and ethnic groups with AF had a lower risk of AF/AFL-related acute healthcare utilization postablation.
