Influence of temperature and storage time on microplastic release from packaged sausages.
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
This study investigated the microplastics (MPs) release in chicken sausages before and after packaging for 180 days of storage at -18 °C-4 °C. Samples were digested in 10% KOH at 50 °C, filtered (0.6 μm), and MPs characteristics (color, shape and size) were determined by optical microscope. The polymer type and elemental composition of MPs were determined by Confocal-Raman-Spectroscopy and SEM-EDX, respectively. MPs release was significantly higher at 4 °C than at -18 °C. The isolated MPs were in fibrous shape ranging from 50 to 1500 μm in length; and transparent color constituted the predominant fraction. Detected polymers were polypropylene, polycarbonate and polyamide. The highest estimated daily intake (EDI) corresponded to sausages held at 4 °C with 55% meat content. MPs release was influenced by meat percentage, storage time and temperature. These findings underline the need for further research on the long-term health implications of MPs exposure through processed meat products.
