Fabrication of gold/silver nanodimer SERS probes for the simultaneous detection of Salmonella typhimurium and Staphylococcus aureus.
Article in Mikrochimica acta, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
Salmonella typhimurium (S. typhimurium) and Staphylococcus aureus (S. aureus) are the two most important foodborne pathogens which can easily cause disease infections. Here, the aptamer-facilitated gold/silver nanodimer SERS probes were built for the simultaneous detection of the two bacteria with the help of magnetic separation enrichment. First, two nanodimer SERS signal probes and two magnetic capture probes each connected with the specific aptamer were fabricated. The distance between gold and silver nanoparticles in the dimer can amplify the Raman signal (Cy3 and Rox) at the junction but modified in the aptamer sequence. Then, after the addition of S. typhimurium and S. aureus, the sandwich-like composite structures "SERS signal probes-target-magnetic capture probes" formed because of the high affinity between aptamer sequences and their target bacteria. Under the optimal experimental conditions, the linear correlations between Raman intensity and the logarithm of the concentration of bacteria were y = 876.95x-67.84 (R
