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: Balloon ablation for pulmonary vein isolation (PVI) is a well-established treatment option for atrial fibrillation. Although some patients require touch-up ablation, generalizable evidence is limited. Objective: This study aimed to investigate the current status and outcomes of touch-up applications using a nationwide registry in Japan. Methods: Patients ≥18 years of age who underwent first-time PVI between January 2017 and December 2020 were included using the data from the Japanese Catheter Ablation registry. The annual trends in the proportion of cases requiring touch-up ablation with radiofrequency ablation were determined, and the associations of ablation strategies with acute success and periprocedural complications were analyzed using logistic regression analysis. Results: Of the 51,402 patients included, 28,412 and 22,990 patients underwent PVI using radiofrequency ablation and balloon ablation, respectively. In the balloon ablation group, 1462 (6.4%) patients required touch-up applications, and the proportion of cases requiring touch-up applications decreased during the study period from 9.5% in 2017 to 5.5% in 2020 ( Conclusion: Touch-up applications following balloon ablation are required in some cases. Touch-up ablation with radiofrequency ablation may be a treatment option when achieving successful PVI using balloon ablation is difficult.
