Optimal ablation index parameters for radiofrequency ablation therapy of atrial fibrillation.
Article in Pakistan journal of medical sciences. 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
Objectives: To explore the optimal ablation index (AI) parameters for radiofrequency catheter ablation (RA) for treating atrial fibrillation (AF). Methods: Patients with AF (186) who underwent bilateral PVAI in the Department of Cardiology, Zhuhai People's Hospital, Guangdong Province, from March 2018 to October 2019 and received catheter ablation as first-round treatment, were grouped according to the received AI. Control group included patients (95) who received the recommended AI ablation (350-400 for posterior wall, 400-450 for non-posterior wall). Patients in optimal AI group were ablated with optimal AI (300-330 for posterior wall, 350-380 for non-posterior wall). Recurrence was defined as any AF, atrial tachycardia, or atrial flutter lasting more than 30 seconds without anti-arrhythmic drugs after the 3-month blank period. Results: Of 186 patients, 66 patients had paroxysmal atrial fibrillation and a mean CHA Conclusion: Radiofrequency ablation of AF, guided by optimal AI combined with impedance, can minimize atrial injury, prevent atrial failure, promote the recovery of atrial function, reduces intraoperative cough, pain, and postoperative gastrointestinal discomfort and use of PPIs.
