1 · What the graph read from it

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.

2 · The registry

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

Bio-derived NiO-Carbon nanocomposites were prepared using Neem (Azadirachta indica) leaf extract through a green combustion approach. Structural analysis confirmed the formation of face-centered cubic NiO with crystallite sizes in the 25-50 nm range. The optimized 1:1 NiO: C composite demonstrated a limit of detection calculated via the 3σ/slope method in the millimolar range, along with a linear sensing response between 1 and 6 mM for glyphosate. In addition, the material achieved 98.78% degradation of Congo Red (CR dye) under UV irradiation (365 nm, 15 mW/cm²) while maintaining strong reusability and stability. The improved performance is attributed to the presence of conductive carbon, which facilitates charge transport, reduces electron-hole recombination, and increases the availability of active surface sites. Electrochemical impedance analysis further confirmed reduced charge-transfer resistance in the optimized composite, supporting its enhanced interfacial kinetics. The scalable and cost-effective synthesis, combined with stability in acidic media, highlights the potential of this composite as a multifunctional platform for pesticide monitoring and wastewater remediation.
