N-doped carbon quantum dots for the detection of 4-nitrophenol, antioxidant activity, and synthesis of Fe
Article in RSC advances, 2026. 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
In this work, raw turmeric and l-arginine were used as the source in the hydrothermal process to synthesize nitrogen-doped carbon quantum dots (NCQDs) in an environmentally friendly, greener manner. Because of their excellent photoluminescence, quantum yield of 36.40%, and their water solubility, the NCQDs were investigated for their multifunctional applications. As a result, they were used as a sensor for the selective detection of 4-nitrophenol (4-NP). 30 nM was determined to be the limit of detection (LoD). It also shows strong antioxidant efficacy, which was evaluated using DPPH free radical scavenging. Additionally, the NCQDs stabilized the synthesis of the FeO
