Novel Electrochemical Sensing Strategy for Organophosphorus Pesticide Residues.
Article in Biosensors, 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
Organophosphorus pesticide residues (OPPs) pose significant threats to ecological systems and human health, and conventional detection techniques are cumbersome, time-consuming, and costly. Herein, a facile electrochemical biosensor has been constructed based on a methyl green/chitosan (MG/Chi) composite membrane-modified electrode for the selective detection of OPPs, using isazofos (Isa) as the model analyte. Experimental results demonstrated that Isa significantly decreases the redox peak current of the modified electrode in buffer solution, and a good linear relationship was observed between the change in peak current and Isa concentration within a specific range. This biosensor exhibits excellent anti-interference capability and high sensitivity, with a limit of detection (LOD) as low as 0.60 μM. Furthermore, it was successfully applied for the quantitative determination of OPPs in real food and environmental samples, which confirms its reliable practical applicability and potential for on-site monitoring.
