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 response to the demand for hydrogen safety monitoring, this study proposes an optical hydrogen sensor based on surface plasmon resonance enhancement. Traditional palladium film optical sensors have problems such as weak response and susceptibility to interference. This design innovatively uses low refractive index magnesium fluoride as the substrate and combines it with a periodic palladium nanopore array structure. Finite-difference time-domain simulation shows that the structure exhibits a significant redshift in the reflection spectrum after hydrogen adsorption and an increase in reflectivity, with a sensitivity superior to that of traditional planar palladium films. The nanopore array enhances the optical response through local field enhancement and surface lattice resonance coupling. The magnesium fluoride substrate, with low optical loss and excellent light transmittance, further optimizes the plasmon resonance performance. This study provides a new approach for the development of highly sensitive, fast-response, and intrinsically safe hydrogen sensors.
