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

Planar polaritonic lenses, achieved by precisely controlling interface polaritons, hold significant promise for subwavelength light focusing. While most existing designs rely on polariton interference or refraction, creating gradient-index polaritonic lenses remains a substantial challenge due to the lack of practical and cost-effective fabrication methods. Here, we introduce a lithography-free approach for producing polaritonic lenses with gradient effective refractive indices by engineering the dielectric environment of polaritons. This method involves in situ transformation of polymer microspheres into spherical caps through controlled melting, allowing the fabrication of polaritonic Luneburg lenses with focal spots as small as λ
