Ascorbic acid stabilised copper nanoclusters as fluorescent sensors for detection of quercetin.
Article in RSC advances, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
In this report, green-emitting fluorescence copper nanoclusters (Cu NCs) were synthesized using ascorbic acid as reducing agent and protecting agent. The ascorbic acid capped Cu NCs (AA-Cu NCs) were characterized using fluorescence spectroscopy, UV-vis absorption spectroscopy, Fourier Transform Infrared Spectroscopy (FT-IR), Transmission Electron Microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The analysis data demonstrated that the AA-Cu NCs were highly dispersed with an average diameter of 2 nm. The as-prepared Cu NCs possessed good water solubility, excellent photostability and displayed excitation-dependent fluorescence characteristics. More importantly, the fluorescence intensity of AA-Cu NCs was linearly quenched in the presence of quercetin from 0.7 to 50 μM and the detection limit (LOD) was 0.19 μM. Finally, the fluorescence sensor was successfully employed to detect quercetin in bovine serum samples.
