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: Various methods have been devised for catheter ablation of persistent atrial fibrillation (AF). However, it remains difficult to understand the mechanism of AF and to determine the optimal method. Objective: This study aimed to evaluate the effectiveness of rotor modification (RM) compared to posterior wall isolation (PWI) in the treatment of persistent AF. Methods: The study included 50 patients in the RM group (mean age: 67.0 ± 8.7 years; 76% with long-standing persistent AF) and 50 patients in the PWI group (mean age: 66.8 ± 8.9 years; 66%). In the RM group, in addition to cryoballoon isolation of the pulmonary veins, rotors in both atria were identified using a phase mapping system and ablated at low power. In the PWI group, the pulmonary vein antrum and posterior wall were isolated together using a radiofrequency catheter. The primary end point was the maintenance of sinus rhythm, defined as freedom from atrial tachycardia, AF, and atrial flutter over a 36-month postoperative follow-up period. Results: Survival curve analysis using the log-rank test revealed a statistically significant difference ( Conclusion: RM is suggested to be as effective as PWI or more effective in maintaining sinus rhythm in patients with persistent AF.
