Methodology, characterization, and multiple-path particle dosimetry modeling of laboratory inhalation exposure for micro-nanoplastic particles in rodents.

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
Plastics are ubiquitous in all trophic environments. Human exposures primarily occur via ingestion, inhalation, and/or injection routes. However, laboratory models of micro- and nanoplastic (MNP) particle exposures replicating the human condition remain inconsistent and uncharacterized, thus limiting study strength and compromising the reliability of results. The purpose of this study was to thoroughly optimize and characterize an established methodology for MNP rodent inhalation exposures, and to model particle respiratory deposition to estimate theoretical in silico exposures in rats and humans for the assessment of MNP health effects. Using our whole-body rodent inhalation facility, we generated MNP aerosols after thorough material characterization of a commercially available food-grade polyamide-12 (PA-12) bulk microparticle powder. PA-12 particulate was thoroughly assessed via pyrolysis-gas chromatography-mass spectrometry (PY-GC-MS), attenuated total reflectance-Fourier-transform infrared (ATR-FTIR) spectroscopy, and helium ion microscopy (HIM) to confirm material chemistry, size, and surface shape. Representative MNP were established and measured at three mass concentrations, low (1.01 mg/m
