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: Same-day discharge (SDD) after atrial fibrillation (AF) ablation is generally considered safe, since most complications are identified during (or immediately) after the procedure. Objective: This study aimed to evaluate SDD in the SPHERE Persistent-Atrial Fibrillation trial. Methods: Patients with persistent AF were randomized to the dual-energy lattice-tip mapping and ablation catheter (investigational) vs a conventional contact-force radiofrequency ablation system (control). SDD and timing of 30-day procedure- or device-related serious adverse events (SAEs) were assessed in the full cohort. In a subset of centers that performed SDD in the trial, predictors of SDD, 30-day readmissions, and mortality rates were assessed. Results: SDD was achieved in 229 of 418 (54.8%) patients (55.9% of investigational [n = 211] and 53.6% of control [n = 207; Conclusion: Among the traditional thermal ablation technologies, SDD protocols have been well-established and safely practiced. Here, SDD was safely achieved, with no significant differences in outcome when performed with the investigational system compared with a conventional contact-force radiofrequency ablation system.
