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

backgroundMicroplastics (MPs) are emerging environmental contaminants with potential hepatotoxicity, yet direct epidemiological evidence linking internal MP exposure to liver injury is scarce, particularly in individuals with type 2 diabetes (T2D). In this cross-sectional study nested within the METAL2 cohort, we aimed to characterize blood microplastic profiles in patients with T2D and to determine whether specific MP polymers are associated with hepatic steatosis and fibrosis risk, with experimental validation of the identified polymer.

resultsIn patients with T2D, multiple MP polymers were detectable in blood, with polyvinyl chloride (PVC), polyamide 66 (PA66), and polystyrene (PS) being the most prevalent. Although PVC constituted the largest proportion of total MP burden, PS showed the most consistent nominal positive liver-related signal in the human analyses, including higher levels in participants with elevated fibrosis risk and higher FIB-4 and ALT in the highest exposure quartile. Experimental validation in diabetic mice demonstrated that PS microplastics markedly exacerbated hepatic steatosis, inflammation, and collagen deposition, leading to overt liver fibrosis. Mechanistically, PS-MPs exposure disrupted hepatic lipid homeostasis and concurrently activated the NLRP3 inflammasome and the TGF-β1/Smad signaling pathway, promoting inflammatory amplification and hepatic stellate cell activation.

conclusionThis integrated human and experimental study provides preliminary evidence that circulating PS-associated signals are linked to liver-related indices in T2D, while experimental findings support the biological plausibility that PS exposure may aggravate hepatic injury under diabetic conditions.
