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

Surface-enhanced Raman scattering (SERS) has been widely applied to food safety screening owing to its high sensitivity and fingerprint recognition. However, SERS faces challenges in practical applications related to the precise control of the number of hot spots and the determination of how many of them actually contribute to the collected signal. In this study, silver nanoparticles (AgNPs) were used to construct a series of layer-tunable AgNP film structures by assembling one to five layers of AgNP thin films using a liquid-liquid interface self-assembly method to obtain a large number of vertically coupled nanogap structures. The relationship between the stacking number and the effective enhancement was evaluated using crystal violet as a probe molecule. The results showed that the SERS intensity increased from one to three layers and then declined, mainly originating from the competition between the vertical plasmon coupling and the finite optical penetration depth; the point-to-point relative standard deviation of the crystal violet signal at 1617 cm
