1 · What the graph read from it

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.

2 · The registry

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

Mercury (Hg) is a global contaminant that biomagnifies in food webs, raising concerns for food safety, fisheries exploitation, and wildlife conservation. Fish, including apex predators like sharks, are the primary source of human Hg exposure, yet species-specific speciation data remain scarce. Most studies rely on total Hg (THg) as a proxy for methylmercury (MeHg), but direct MeHg measurement is essential for accurate risk assessment due to neurotoxicity and bioavailability. This study presents a comprehensive assessment, quantifying THg-MeHg in 18 species from the Mediterranean, Indian, and Atlantic Oceans, nine measured for the first time. Concentrations varied widely, with deep-sea and pelagic sharks showing highest levels. THg and MeHg strongly correlated (R
