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

Metal nanoparticles have attracted great interest because of their unique near-field enhancement properties, and have important applications in many fields, such as surface-enhanced Raman scattering (SERS), fluorescence enhancement, solar cell efficiency enhancement and so on. In this paper, we use the finite element method to study the local field enhancement characteristics of the coupling system in which the gold ellipsoidal nanoparticles (GENP) on a mirror. In the coupling system, a hot spot will be formed at the gap between the GENP and the mirror under the appropriate incident light excitation. Based on the structural characteristics of GENP, we systematically study the local electric field produced by placing ellipsoids vertically and horizontally on the mirror. Under the excitation of the same polarized incident light, the maximum local electric field of the vertical GENP is 2200 (V/m), while that of the horizontal GENP is more than 9400 (V/m). Our proposed gap coupling system based on metal nanoparticles and thin films may open a new field of interest in the fields of plasmon, sensing, optical limitation and enhancement.
