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

A multifunctional surface-enhanced Raman scattering (SERS) sensor was initially developed by integrating MXene with Au nanoparticles (MXene/Au) and plasmonic metal composite (Au@Ag NFs) as the substrate, combined with aptamers (apt) and signal molecules (4-MBA) for sensitively recognizing S. aureus in milk products. Firstly, MXene possesses the characteristic of a large specific surface area. On the one hand, it provides a higher number of attachment sites for the plasmonic metal composite, enabling the metal nanoparticles to be uniformly distributed on its surface. On the other hand, it exhibits a pre-enrichment effect for the target bacteria, remarkably enhancing the sensitivity of the SERS sensor. Secondly, Au@Ag NFs/4-MBA coupled with MXene/Au produced a synergistic electromagnetic (EM) enhancement effect, which greatly enhanced the SERS intensity and amplified the Raman signal. Furthermore, the thiol-modified aptamer (SH-apt) dramatically enhances the specificity of the SERS sensor system. Based on the sandwich-structured MXene/Au-apt-Au@Ag NFs/4-MBA, S. aureus can be detected with high sensitivity, achieving a low limit of detection of 1.009 CFU/mL and a broad linear detection range from 10 to 10
