First assessment of microplastic consumption in sympatric black bass species in a temperate river system.
Article in Journal of fish biology, 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
Microplastics (i.e. plastic particles ranging in size from 1 μm to 5 mm) are an understudied emerging pollutant in rural rivers that may pose significant health risks to organisms, and their monitoring is resource-intensive and costly. This study quantifies microplastic consumption in the Monongahela River, West Virginia, USA in three sympatric black bass species: largemouth bass (Micropterus nigricans), smallmouth bass (Micropterus dolomieu) and spotted bass (Micropterus punctulatus). Utilizing an existing sampling program and low-cost methodology, the spatial variability of microplastic ingestion between navigational pools within the Monongahela River and limited temporal variability within a pool was examined to determine differences between the sympatric species in total and shape-size fractions. Microplastics were found in all fish surveyed and Bayesian regression models revealed that microplastic consumption is influenced by species, spatial location and temporal factors, with significant interspecies and intraspecies differences in microplastic consumption. The results emphasize the variability that exists even among similar species and reinforce the need to monitor microplastic pollution in rural river systems to evaluate the ecological risks of microplastic pollution.
