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
Oxidative aging can modify the physicochemical properties of micro- and nanoplastics (MNPs), altering their environmental behavior and potential biological interactions. In this study, we investigated how a hydroxyl radical-driven Fenton oxidation process affects the morphology, size distribution, and surface chemistry of polyvinyl chloride (PVC) and polyamide-12 (PA-12) MNPs using multimodal characterization. Oxidation caused extensive aggregation and surface restructuring in PVC, whereas PA-12 retained greater colloidal stability but showed clear evidence of surface oxidation. Both polymers exhibited increases in oxygen-containing functional groups, along with polymer-specific elemental loss consistent with dechlorination in PVC and amide degradation in PA-12. These transformations indicate that oxidative aging can generate nanoscale debris, increase surface reactivity, and shift particle behavior in ways relevant to environmental fate and human exposure pathways. The results emphasize the importance of including chemically aged MNPs, rather than only pristine particles, in studies examining transport, sorption, and toxicological potential, particularly in contexts where advanced oxidation treatments are used. Overall, this work highlights polymer-specific differences in oxidative transformation and provides a foundation for future studies that connect degradation chemistry with exposure and risk assessment.
