Sensitive Detection of Copper(II) Ions in Water Using Nitrogen-Doped Carbon Quantum Dots Synthesized from Pine Cone Lignin and Lysine.
Article in ACS omega, 2026. 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
The accurate and rapid determination of trace copper Cu-(II) ions in environmental water is of great significance for both ecological safety and human health. In this work, a novel, eco-friendly, and highly sensitive fluorescence sensor was developed using carbon dots synthesized from pine cone deep eutectic solvent (DES) lignin and doped with lysine for the selective detection of Cu-(II) ions. The synthesized carbon dots exhibited excellent optical properties. They demonstrated a strong, concentration-dependent fluorescence response to Cu-(II) with a wide linear range of 2.81 × 10
