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

Topological photonic structures exhibit resilience to defects, allowing unidirectional light flow and promoting the development of robust devices with large information processing capacities. However, the diversity of topological boundary modes is typically governed by bulk-edge correspondence, which limits multidimensional multiplexing and the integration density of next-generation photonic systems. Here, we present a polycrystal approach based on domain wall engineering to configure multi-band dispersion in a synthetic hybrid dimension by utilizing orientation freedom. As a prototype, we demonstrate that an all-dielectric platform for hybrid topological polycrystalline photonic integrated circuits can support up to eight edge channels and four corner modes via pseudospin-valley Hall effect, empowering controllable directionality of multi-frequency and spinful channels with highly localized performance. Our findings reveal a photonic architecture that significantly advances the on-chip integration of topological photonics, offering valuable potential for future information processing technologies across optical and microwave frequencies.
