Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
We introduce and high-performance multilayer surface plasmon resonance (SPR) biosensor based on a hybrid gold (Au), molybdenum disulfide (MoS₂), and graphene structure, specifically engineered to deliver enhanced refractive index sensing performance. The Au layer facilitates efficient plasmon excitation, the MoS₂ layer maximizes electromagnetic field confinement, and the graphene monolayer enhances both light-matter interaction and molecular adsorption. Simulations conducted at a wavelength of 633 nm reveal high sensitivities of 80.0°/RIU for phosphate-buffered saline (PBS) (FOM = 28.57, FWHM = 2.80°), 80.0°/RIU for sucrose solution (FOM = 37.74, FWHM = 2.12°), 78.6°/RIU for blood samples (FOM = 29.87, FWHM = 2.63°), and 80.7°/RIU for glycerol (FOM = 36.19, FWHM = 2.23°), with the latter representing the best performance achieved in this work. These simulation outcomes surpass some previously reported designs, thereby validating the improved plasmonic coupling and field localization capabilities of the proposed sensor. The combination of high sensitivity, stability, and synergistic material properties makes the Au-MoS₂-graphene configuration a promising candidate for next-generation biosensing and chemical detection platforms demanding ultra-sensitive and rapid performance. "These results indicate strong potential for experimental realization in high-sensitivity biosensing and chemical detection applications," which clearly links the simulation outcomes to their practical implications.
