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

As plastic waste breaks down into smaller fragments in the environment, it poses a significant threat to both terrestrial and aquatic ecosystems as well as exposed humans via contaminated water, air, and food. There is thus a critical need to understand the biological uptake and subsequent impacts of plastic particles in aquatic and terrestrial organisms. Yet, we lack effective and robust methodologies to identify and localize micrometer and nanometer-sized polymer particles in whole organisms. This proof-of-concept study introduces a label-free approach for the localization and identification of plastic particles within organisms utilizing optical photothermal infrared microscopy (O-PTIR) and microtome techniques. By integrating O-PTIR imaging with microtomy, we achieved high spatial resolution and sensitivity, allowing us to detect and identify different plastic particles (polystyrene, polyethylene, polypropylene, and poly(methyl methacrylate)) and confirm their localization in a tissue sample. The results demonstrate successful visualization of microplastics and nanoplastics at moderate exposure concentrations in a range of aquatic and terrestrial organisms; namely,
