Pen-on-Paper Label-Free Surface-Enhanced Raman Scattering (SERS) Detection of Tetracycline in Milk.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Monitoring food quality requires the development of low-cost and sensitive analytical tools with label-free and point-of-site detection capabilities. Surface-enhanced Raman scattering (SERS) is a powerful analytical technique that combines fingerprint detection capabilities with high sensitivity. In this paper, we present the pen-on-paper fabrication of SERS substrates, whereby plasmonic nanoinks were written on a paper substrate and used for the detection of food contaminant residues. To construct sensitive and robust SERS sensors, four different nanoinks with different plasmonic properties were synthesized and tested on eight papers of different weights, textures, and hydrophilicities. The combination of silver nanoink and Bristol printing paper resulted in the strongest SERS substrate, which was used for crystal violet (CV) and tetracycline detection. Concentrations as low as 10
