Atrial fibrillation burden and symptom, quality of life, and healthcare resource utilization after cryoballoon ablation in persistent 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
aimsTo investigate the relationship between continuously monitored atrial fibrillation (AF) burden after cryoballoon ablation (CBA) and improvements in AF-related symptoms, quality of life (QoL), and AF-related healthcare resource utilization (HCRU) in early persistent AF. METHODS AND
resultsThis secondary analysis of the multicentre COOL-PER trial included patients with early persistent AF who underwent CBA and continuous monitoring via an implantable loop recorder. Post-CBA AF burden was defined as the percentage of time in AF between 9- and 12-month after CBA, categorized as <0.1%, 0.1 to <10%, and ≥10%. Symptom improvement was assessed using the European Heart Rhythm Association symptom score and QoL with the SF-36 survey. AF-related HCRU was defined as rhythm control interventions after the 90-day blanking period and cardiovascular-related hospitalizations or emergency room visits. Among 130 patients (mean baseline AF burden 77 ± 34%), AF burden significantly decreased post-CBA, with 50.0% achieving <0.1%, 28.5% in 0.1 to <10%, and 21.5% ≥ 10%. Symptom improvement rate was highest in the <0.1% group (89.2%), followed by the 0.1 to <10% (78.4%) and ≥10% (46.4%) groups (P < 0.001). Significant QoL improvement was observed in the <0.1% and 0.1 to <10% groups but not in the ≥10% group. Rhythm control interventions and cardiovascular-related hospitalizations or emergency room visits were more frequent in the ≥10% group (29%, 43%) than in the 0.1 to <10% (5.4%, 22%) and <0.1% (1.5%, 7.7%) groups (both P < 0.001).
conclusionIn early persistent AF, lower AF burden 1-year post-CBA was associated with greater AF-related symptom improvement, significant QoL enhancement, and reduced HCRU during follow-up.
