Global seafood production practices and trade patterns contribute to disparities in exposure to methylmercury.
Article in Nature food, 2025. 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
Seafood consumption is a major pathway for exposure to methylmercury (MeHg), a globally pervasive neurotoxin. Yet, how upstream processes in the seafood value chain influence MeHg exposure remains poorly understood. Here we quantified MeHg in seafood production, trade and consumption in 2019 around the world. We found that countries with seafood-MeHg exposures beyond the recommended threshold by the World Health Organization were predominately high-income countries. These countries experienced a tenfold increase in exposure levels compared with low-income countries, due to greater consumption and long-overlooked higher MeHg concentrations in seafood inherited from production. Notably, 43% of seafood MeHg in production was redistributed through seafood trade, marked by inequality, as exports from high-income to lower-income countries contained higher seafood-MeHg concentrations. These exposures may have resulted in 61,800 global premature deaths and economic losses of around US$2.87 trillion, underscoring the need to change seafood production practices and trade patterns.
