Methanogenesis couples with arsenic methylation in urban interface biofilms under arsenic-phosphorus decoupling stress.
Article in Frontiers in microbiology, 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
Introduction: Urban interface biofilms represent understudied microenvironments where atmospheric deposition, microbial colonization, and stormwater runoff intersect, yet their role in contaminant transformation and greenhouse gas dynamics remains poorly understood. Methods: Here, we investigated arsenic-phosphorus biogeochemistry and microbial functional gene dynamics across 18 urban interface sites. Results: We discovered a striking arsenic-phosphorus decoupling pattern, with industrial sites exhibiting high arsenic (92.1 mg kg Discussion: These findings establish urban interfaces as previously unrecognized hotspots where arsenic transformation and greenhouse gas production are mechanistically coupled, with important implications for understanding urban biogeochemical cycles and their environmental impacts.
