Real-world sex differences in healthcare utilization after cryoballoon ablation: 2-year outcomes from the Cryo Global Registry.
Article in Frontiers in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02752737 (Cryo Global Registry, a Part of the Medtronic Cardiac Ablation Post-Market Study Platform), which is not on this map.

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

Abstract
Introduction: Cryoballoon ablation (CBA) is a well-established treatment for atrial fibrillation (AF). However, evidence on the impact of sex on outcome is sparse. This real-world analysis aims to describe outcome after CBA in both sexes. Methods: This registry is an ongoing, global evaluation of CBA procedures in standard-of-care practice. Females undergoing CBA were compared to males at baseline and 12-, and 24-months post-ablation. Serious procedure-related adverse event rate, rate of atrial arrhythmia (AA) recurrence, repeat ablation, hospitalization, cardioversion, and quality-of-life (QoL; EQ-5D-3l) were compared. Results: Of 3,089 patients with 12-month follow-up, 1,136 (36.8%) were female; and a subset of 1,099 patients (400 female) were followed through 24 months. Females presented with different comorbidities at baseline. The complication rate was low overall in females (3.9%) and males (2.7%, Discussion: CBA performed according to standard-of-care practice was safe in both sexes. The efficacy of CBA is marginally lower in females, but 75% of females remained free from AA recurrence at 24-months and reported a meaningful improvement in QoL post ablation.
