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: Transcatheter atrial septal defect (ASD) closure is a minimally invasive procedure, yet variability in right heart reverse remodeling post-procedure remains understudied. Objective: To evaluate the impact of transcatheter ASD closure on right ventricular (RV) parameters and tricuspid regurgitation (TR) severity over six months, and to identify predictors of RV reverse remodeling and TR improvement. Methods: This prospective study included 60 adult patients who underwent successful transcatheter ASD closure. Transthoracic echocardiography was performed at baseline, and at 1, 3, and 6 months post-procedure to assess RV dimensions, systolic function, and TR severity. Results: Significant reductions were observed in RV dimensions-including tricuspid annular diameter, RV basal diameter, RV mid-cavity diameter, and RV outflow tract diameter-at 6 months ( Conclusion: Transcatheter ASD closure leads to significant right heart reverse remodeling and TR improvement. Younger age, sinus rhythm, and smaller preprocedural chamber dimensions predict RV reverse remodeling and improvement of TR, supporting their role in patient selection and clinical decision-making.
