Screening for malachite green contamination on live fish skin with chewing gum based viscoelastic SERS sensor.
Article in Journal of food and drug analysis, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Malachite green (MG), a prohibited but still found antimicrobial in aquafarm and during live fish shipping, is a hot target in food safety screening. Herein, a novel chewing gum based flexible SERS (G-SERS) sensor was proposed for rapid sampling and detection of MG on live fish skin. The whole analysis takes <5 min, while the limit of detection for MG is 0.73 pg. Different from other reports, MG contaminated live fish was monitored daily with the G-SERS sensor, during which the fish was firstly raised in 0.5 ppm MG solution for one day, followed by freshwater for a week. It was found that the SERS signal of residue MG on fish skin could still be seen even on the sixth day, roughly the sale cycle of live fish in a marketplace. Furthermore, the method was also applied for MG screening on the skin of fish purchased from a supermarket and a local street marketplace. MG was found on some fishes from the latter but not from the former, which was cross-validated by LC-MS, suggesting MG risks still exist in smaller marketplaces. This work demonstrated the feasibility of using the flexible SERS sensor for onsite food safety screening.
