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

backgroundTransseptal puncture (TSP) is required for most catheter ablation (CA) procedures for atrial fibrillation (AF) because it enables left atrial access. In patients with atrial septal occluder (ASO) devices, device-related changes in septal anatomy may affect procedural planning, feasibility, and safety. We performed an updated systematic review and meta-analysis to evaluate reported outcomes of TSP-assisted CA in patients with ASO.

methodsWe searched PubMed, Embase, and the Cochrane Library from inception to April 28, 2026, including studies evaluating TSP-assisted CA in patients with ASO. Outcomes were AF recurrence, periprocedural complications, and procedural success, reported as proportions with 95% confidence intervals (CIs).

resultsNine observational studies comprising 207 patients were included (36.7% female; mean age, 47.9 years; mean follow-up, 21.5 months). AF recurrence had a pooled incidence of 23.95% (95% CI 18.08% to 31.00%; I

conclusionObservational evidence suggests that TSP-assisted CA in patients with ASO is feasible and has a low reported complication rate in experienced centers, although the certainty of these findings is limited by small, noncomparative studies.
