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 study, an injectable artificial photoreceptor (APR) is engineered to transduce visible light into cell-level electrical stimulation via localized surface plasmon resonance to restore vision in patients with vision loss. APRs comprise gold nanoparticles (AuNPs) with poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) dielectric coating and are integrated onto a high-permittivity barium titanate core. This yields a stable nanocomposite with maximum absorbance in the green band at around 525 nm. APRs were evaluated in vitro using human pluripotent stem cell-derived retinal ganglion cells (hRGCs) exposed to light stimulation. In vivo efficacy was assessed following intravitreal injection of APRs in the
