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

This report presents the first-in-human experience with a 3-dimensional controlled-bending, fully retrievable delivery system for transfemoral transcatheter aortic valve replacement in severe aortic stenosis with anatomical challenge. In a prospective single-center series (September-December 2023) of 6 high-risk patients (mean age: 68.0 ± 3.9 years, 84% bicuspid valve, all with complex features such as horizontal heart or dilated ascending aorta), the device success rate was 100%, implantation was coaxial (implantation depth difference: 2.32 ± 1.53 mm), and postprocedural paravalvular leak was none to trivial. Hemodynamics improved substantially (gradient decreased from 75.5 ± 12.3 to 7.9 ± 2.1 mm Hg, effective orifice area increased from 0.61 ± 0.15 to 2.26 ± 0.34 cm
