Plastic pollution in the Amazon: The first comprehensive and structured scoping review.
Article in Ambio, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 is a global One Health crisis, yet research has focused largely on marine environments. The Amazon-the world's largest drainage basin and second most plastic-polluted river-has received limited scientific attention. This scoping review is the first to apply a systematic protocol (PRISMA-ScR) to assess plastic contamination across Amazonian ecosystems. We reviewed 52 peer-reviewed studies reporting plastic litter and fragments in terrestrial and aquatic environments of the biome. Most evidence concerns microplastics in Brazilian sites along the main Amazon River, with a focus on fish. However, plastics were also found in sediments, plants, and diverse fauna including birds, reptiles, and mammals. No studies reported nanoplastics. The contamination of key food and water sources poses a major One Health risk for traditional populations. We identify urgent research gaps-especially in non-fish fauna, tributaries, and other Amazonian countries-and highlight the need for targeted mitigation through waste management and education.
