Hybrid electromagnetic toroidal vortices.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
The ubiquitous occurrence of toroidal vortices, or vortex rings, in fluid dynamics scenarios in nature has garnered notable attention in the scientific community, while their electromagnetic counterparts have only been proposed recently with two distinct manifestations: vector toroidal pulses and scalar phase toroidal vortices. Herein, we theoretically propose a form of electromagnetic toroidal vortex solutions that uniquely integrates both scalar and vector characteristics, challenging the prevailing notion of their mutual exclusivity. We also present an experimental generation of hybrid toroidal vortex pulses by a compact coaxial horn emitter augmented with a radial metasurface. These topological pulses exhibit peculiar electromagnetic features, such as vortex streets, skyrmions, and transverse orbital angular momentum, and may present advantages when propagating through perturbations, opening avenues for enhanced free-space information transmission, topologically nontrivial light-matter interaction, and microscopy techniques.
