1 · What the graph read from it

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.

2 · The registry

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: General anesthesia (GA) in radiofrequency ablation (RFA) for atrial fibrillation (AF) increases single procedure success rates and shortens procedure times vs conscious sedation (CS). In addition, high-frequency jet ventilation (HFJV) is associated with lower AF recurrence rates than conventional ventilation. Little data exist regarding the impact of sedation strategy on objective catheter stability and how this affects outcomes. Objective: This study aimed to (1) measure catheter stability using the standard deviation (SD) of XYZ coordinates of catheter location, obtained in patients undergoing RFA for AF, and (2) compare catheter stability in CS, GA, and GA + HFJV groups. Methods: All patients who underwent AF RFA at our center from April 2023 to June 2024 were eligible for inclusion in the study. Catheter stability was assessed using XYZ coordinates of catheter location, obtained via the CARTO 3 VisiTag module. The median SD of XYZ coordinates per ablation lesion was used to determine catheter stability. Results: A total of 28 patients were included in the study, 8 in the CS group, 10 in the GA group, and 10 in the GA + HFJV group; 1,979,105 XYZ coordinates of RFA catheter location were analyzed. GA demonstrated an improvement in catheter stability compared with CS (median [interquartile range]) (0.54 [0.3-0.89] vs 1.51 [0.95-2.3], Conclusion: The SD of XYZ coordinates of catheter location, obtained via the CARTO 3 VisiTag module, can be used to assess catheter stability during AF RFA. GA + HFJV offers superior catheter stability compared with GA and CS.
