Antimicrobial resistomes in plastisphere-associated microbes over aged low-density polyethylene microplastics in the Haora River of Tripura, India.
Article in Water environment research : a research publication of the Water Environment Federation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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 (MPs) provide favorable ecological niches for antimicrobial resistance (AMR) development in aquatic ecosystems. Environmental weathering transforms the inert surfaces of MPs into oxygen-functionalized, reactive interfaces that promote plastisphere formation and selective enrichment of antibiotic-resistant microorganisms. However, studies integrating natural polymer weathering, plastisphere development, and resistome profiling under ecologically relevant conditions remain scarce, particularly in South Asian freshwater ecosystems. To address this knowledge gap, low-density polyethylene (LDPE) pellets were incubated in situ in the anthropogenically impacted Haora River of Northeastern India to investigate how environmental aging-induced surface transformations shape plastisphere formation and association of AMR characteristics. Pristine, aged with biofilm, and aged without biofilm LDPE MPs were comparatively analyzed. Weathering significantly increased surface roughness, crystallinity, and carbonyl index, facilitating dense biofilm formation (OD
