Registry for Long-Term Outcomes After Catheter Ablation in Nagano Prefecture - The Shinshu Catheter Ablation (Shinshu-AB) Registry Rationale and Design.
Article in Circulation reports, 2026. 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: Catheter ablation (CA) is a well-established therapy for arrhythmia, but the impact of CA strategies has not been thoroughly investigated. Nagano Prefecture comprises a large geographical area and some hospitals do not have cardiac surgeons, thus limiting the application of CA strategies. The aim of this study was to investigate the detailed strategies for CA in Nagano Prefecture and to clarify their efficacy and safety. Methods and Results: The Shinshu Catheter Ablation (Shinshu-AB) Registry is a multicenter prospective observational registry. Patients treated with CA for any type of arrhythmia are included. Data on the target arrhythmia(s), CA strategy, outcomes, and complications were collected and analyzed at Shinshu University Hospital. The study was approved by the institutional review boards of all investigational sites and registered in the UMIN Clinical Trials Registry (UMIN-55562). Primary endpoints were the composite incidence of arrhythmia recurrence, procedure-related adverse events, and cardiovascular events. The secondary endpoints were acute success, chronic success for >12 months, and all-cause death. Conclusions: The Shinshu-AB Registry provides real-world data from the Nagano Prefecture on the outcomes and complications of CA for various types of arrhythmias.
