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: Circular mapping catheters (CMC) are used to confirm pulmonary vein isolation (PVI) in radiofrequency (RF) ablation for atrial fibrillation (AF), but may be unnecessary in CLOSE-style point-by-point workflows. We evaluated whether omitting the CMC preserves efficacy and improves efficiency in first-time PVI. Methods: We conducted a single-center, hybrid prospective-retrospective comparison of consecutive first-time PVI cases. A CMC-guided cohort ( Results: CMC-free cases had shorter procedures [105 (90, 120) vs. 120 (110, 135) min, Conclusion: In CLOSE-style first-time RF PVI, a CMC-free, single-catheter workflow was associated with improved procedural efficiency and no significant difference in observed 12-month arrhythmia outcomes. These findings are hypothesis-generating. Prospective randomized studies are needed to confirm the safety and efficacy of this approach.
