Radiofrequency ablation vs. cryoablation for pediatric atrioventricular nodal reentrant tachycardia in the era of three-dimensional electroanatomical mapping.
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. Cited by 2 papers.
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: Cryoablation for pediatric atrioventricular nodal reentry tachycardia (AVNRT) is favored for reducing conduction system injury compared to radiofrequency (RF) ablation. The safety advantage of cryoablation over RF ablation primarily results from studies conducted without a three-dimensional electroanatomical mapping (3D EAM) system. Currently, 3D EAM systems offer precise and efficient guidance, improving safety and outcomes. This study compares RF ablation and cryoablation using a 3D EAM system for pediatric AVNRT treatment. Methods: A retrospective study enrolled consecutive pediatric patients with AVNRT who underwent RF ablation (RF group) or cryoablation (Cryo group) guided by a 3D EAM system at multiple centers from July 2018 to January 2024. Results: Among 95 patients, 69 received RF ablation and 26 received cryoablation. Recurrence rates were 2.9% in the RF group and 0% in the Cryo group ( Conclusion: With 3D EAM guidance, both RF ablation and cryoablation are considered safe and effective for pediatric AVNRT. RF ablation is more efficient with a shorter procedure time after increasing experience.
