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

Optical vortices, beams that carry a twist, are pivotal in advanced technologies like optical manipulation, optical communications and imaging. However, their utility has been hampered by a fundamental limitation: the size and spread of the beam change inevitably with its twist and color, making stable, scalable systems difficult to achieve. Here we show that using precisely engineered metasurfaces to control light's radial momentum enables the generation of a class of 'achromatic non-diffracting perfect vortex beams' (ANPVBs). These beams maintain an almost perfectly constant diameter, regardless of their twist or color across the visible spectrum (450-780 nm), and resist spreading over long distances. By decoupling beam size from these previously limiting factors, our work provides a robust and versatile platform for applications in high-capacity optical communication, quantum information processing and imaging.
