Microplastic contamination in remote mountain lakes of the americas: a baseline assessment from Patagonia and Northern California.
Article in Frontiers in toxicology, 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
Plastic pollution and its effects on freshwater ecosystem function are increasingly recognized, with recent research demonstrating that even remote environments are impacted. Despite growing evidence, the relative importance of local versus large-scale transport processes in delivering microplastics (MPs) to remote mountain lakes remains poorly understood. Surface water samples were collected by net trawling in 15 remote mountain lakes, eleven in the Patagonia region of Argentina and four in Northern California, United States, and analyzed by stereomicroscopy and Raman spectroscopy for MP concentration, shape, size, color, and polymer composition. MPs (≥ 80 µm) were detected at all sites, with concentrations ranging from 0.23 to 2.79 particles m
