Sleep Apnea and Abnormal Respiratory Patterns with Deep Sedation during Radiofrequency Catheter Ablation in Patients with Atrial Fibrillation.
Article in Reviews in cardiovascular medicine, 2022. 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
Background: Abnormal respiration during radiofrequency catheter ablation (RFCA) with deep sedation in patients with atrial fibrillation (AF) can affect the procedure's success. However, the respiratory pattern during RFCA with deep sedation remains unclear. This study aimed to investigate abnormal respiration during RFCA and its relationship with sleep apnea in patients with AF. Methods: We included patients with AF who underwent RFCA with cardiorespiratory monitoring using a portable polygraph both at night and during RFCA with deep sedation. The patients were divided based on the administered sedative medicines. Results: We included 40 patients with AF. An overnight sleep study revealed that 27 patients had sleep apnea; among them, 9 showed central predominance. During RFCA with deep sedation, 15 patients showed an abnormal respiratory pattern, with 14 patients showing obstructive predominance. Further, 17 and 23 patients were administered with propofol alone and dexmedetomidine plus propofol, respectively. There was no significant between-group difference in the respiratory event index (REI) at night (7.9 vs. 9.3, Conclusions: Our findings demonstrated that respiratory events during RFCA with deep sedation were mainly obstructive. Propofol should be administered with dexmedetomidine rather than alone to reduce the propofol amount and avoid respiratory instability.
