Quantity of Cu(II) ions in a copper pot by a DNAzyme-based fluorescent sensor.
Article in Food chemistry. Molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Copper deficiency can adversely impact health, and using copper cookware can help supplement copper ions. In this study, we have developed a fluorescent Cu(II) sensor using an efficient DNAzyme, a novel cofactor 2-mercaptoethanol and an optimized fluorophore. This sensor has demonstrated high sensitivity, with a linear detection range of 30 nM-50 μM and a detection limit of 3.4 nM. Furthermore, it has shown high selectivity for Cu(II) ions and possesses excellent anti-interference ability against 10,000-fold excess of Ca(II) and Mg(II),
