High-frequency low-tidal volume ventilation improves long-term success in radiofrequency catheter ablation of atrial fibrillation: a meta-analysis.
Article in European heart journal open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Aims: High-frequency low-tidal volume (HFLTV) ventilation may improve catheter stability and enhance procedural success in radiofrequency (RF) catheter ablation of atrial fibrillation (AF). Long-term findings remained unclear. Methods and results: We conducted a meta-analysis that included all studies that directly compared AF patients who underwent RF ablation under HFLTV compared with standard ventilation. Primary outcomes included acute first-pass pulmonary vein isolation (PVI) and long-term recurrence of AF/atrial arrhythmias after 12 months. Secondary outcomes included total procedure duration, ablation time, and RF time, with pooled standardized mean difference derived using the inverse variance method. Five cohort studies (publication period: 2019-2024) were identified and included in the meta-analysis (final sample: HFLTV Conclusion: High-frequency low-tidal volume ventilation is associated with improved long-term success of arrhythmia control in AF patients who undergo RF catheter ablation, regardless of paroxysmal or persistent status.
