Integrated Study of Polyethylene Microplastic Degradation and Its Interaction with the Insecticide Imidacloprid: Chronic Toxicity to Daphnia similis.
Article in Archives of environmental contamination and toxicology, 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 presence of microplastics (MPs) in freshwater environments represents a growing environmental concern due to their persistence and ability to interact with contaminants such as pesticides. This study evaluated the influence of photodegradation on the toxicity of polyethylene microplastics (PE-MPs), alone and combined with the pesticide Imidacloprid (IMI), on the cladoceran Daphnia similis. Microparticles of polyethylene were aged under UV-C radiation for 94 days and subsequently characterized by Scanning Electron Microscopy (SEM) and Fourier-Transform Infrared Spectroscopy (FTIR). Surface analysis indicated polymer degradation through cracks and cavities, and increased surface roughness, while FTIR analyses showed polymer oxidation. Ecotoxicological results revealed that pristine MPs significantly reduced survival by 90% at 80 mg L
