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

In this work, we developed a 3D computational framework to evaluate the beam transport performance of a static gantry proposed in previous studies. This static gantry enables magnetically driven azimuthal angle selection via tailored fields rather than mechanical rotation, yet its practical feasibility requires rigorous simulation-based evaluation. Our approach utilizes full 3D magnetic field modeling in Opera3D coupled with a custom phase-ellipse tracking program. This integrated workflow captures realistic 3D fringe-field effects and quantitatively evaluates the optical limits driven by momentum spread and boundary edge-focusing. By identifying these primary limitations, this platform provides the requirements and a practical foundation to guide the development and optimization of future static gantry designs.
