Effects of different types of microplastics in soil on nitrogen absorption and metabolism of quinoa.
Article in Scientific reports, 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
To reveal the effects of different types of microplastics (particle size < 5 mm) on crop nitrogen absorption and metabolism, biodegradable microplastics made of polylactic acid (PLA) and polybutylene terephthalate (PBAT) andnonbiodegradable microplastics made ofpolyethylene (PE) were selected for plant pot experiments atthree mass fractions(0.5%, 1% and 3%, respectively). The responses of inorganic nitrogen content, crop growth, nitrogen absorption and nitrogen-metabolizing enzyme activity to soil microplastic pollution in the soil-Chenopodium quinoa system were studied. The results revealed that microplastics significantly limited the decomposition of soil organic carbon (SOC), reduced the accumulation of quinoa nitrate nitrogen (NO
