Relationship Between Social Deprivation and Access to Catheter Ablation for Atrial Fibrillation: A Population-Level Study.

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: Access to catheter ablation for atrial fibrillation (AF) may vary due to social deprivation. Objectives: This study sought to characterize the correlation between our outcomes of interest (rates of AF diagnoses, ablation referrals, and procedures) and the association between social deprivation and our outcomes. Methods: Rates and correlations of AF diagnoses, ablation referrals, and procedures were reported across 49 census divisions in Ontario, Canada. We used the Ontario Marginalization Index to determine the relationship between dependency, material deprivation, ethnic concentration, and residential instability and our outcomes. Results: Between April 2016 and March 2020, there were 146,366 patients diagnosed with AF; 6,506 patients were referred for ablation; and 4,673 patients underwent de novo ablation. The median age was 72 years (IQR: 61-81 years; 45% female) for the AF cohort and 62 years (IQR: 55-69 years, 33% to 34% female) for the referral and procedure cohorts. There was geographic variation and a weak concordance between AF diagnoses, ablation referrals, and procedures (correlation coefficients 0.33-0.36). Increased material deprivation was associated with more AF diagnoses (rate ratio [RR]: 1.13), but fewer ablation referrals (RR: 0.49) and procedures (RR: 0.48). Increased residential instability was associated with more AF diagnoses (RR: 1.02), but fewer ablation referrals (RR: 0.63) and procedures (RR: 0.64). Higher ethnic concentration was associated with fewer AF diagnoses, ablation referrals, and procedures. Conclusions: In a jurisdiction with universal health care, greater material deprivation and residential instability were associated with more AF diagnoses but less access to ablation, suggesting substantial social gradients in equitable access to AF care.
