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

Microplastics (MPs) are pervasive pollutants, subject to environmental ageing processes. This enhances their capacity to adsorb various contaminants from environmental matrices, posing growing threats to both ecosystems and human health. This study investigates the adsorption behaviour and cytotoxicity of 1 μm polystyrene microplastics (mPS), both virgin (v-mPS) and home-aged by thermo-oxidation (ox-mPS), following exposure to wastewater (ww). Hydrodynamic diameter measurements and FTIR analysis revealed significant adsorption of organic and inorganic substances onto v- and ox-mPS, proving the formation of an environmental corona. Approximately, 25% of the entire oxidisable load of the ww, assessed by COD, was adsorbed to the mPS. ww-v-mPS exhibited a higher increase in particle size and a thicker coating due to their hydrophobic nature and affinity for apolar or weakly polar compounds. Conversely, ww-ox-mPS, enriched with polar functional groups, displayed a more moderate increase in diameter. Zeta potential measurements indicated significant adsorption of negatively charged species on v-mPS. In human colorectal cells, both ww-mPS caused cell mortality increases (%Δ 243.3 and 83.2 in v- and ox-mPS in comparison to untreated mPS), highlighting potential risks from ingestion of contaminated food.
