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

A freestanding manganese oxide nanoparticle–decorated laser-induced graphene electrode (MnOx-LIGE) for sensitive electrochemical detection of the organophosphate insecticide fenitrothion (FT) is reported. The electrode is fabricated via a one-step laser-engraving process on MnCl₂-doped polyimide films, enabling the simultaneous formation of porous graphene and in situ decoration with MnOx nanoparticles. Structural characterization confirms a three-dimensional porous graphene network uniformly decorated with MnOx nanoparticles, providing abundant active sites and accelerated electron transfer. Benefiting from this architecture, the MnOx-LIGE exhibits a wide linear detection range from 100.0 nmol/L to 250.0 µmol/L with a low detection limit of 13.66 nmol/L. Integrated with a portable electrochemical workstation, the sensor demonstrates excellent selectivity and stability. It achieves reliable recoveries of 102.4–104.2% in mango samples, highlighting its potential for rapid on-site monitoring of pesticide residues.
