Inorganic contaminants in fish of the Mediterranean Sea: biomonitoring and toxicologic analysis.
Article in Italian journal of food safety, 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
Aquatic systems throughout the world are increasingly under a wide array of anthropogenic stressors, including the release of a myriad of toxic substances into the environment. The presence of twenty-seven heavy metals, vitamins, and minerals was investigated in muscle tissues collected from 46 wild fishes distributed among Thunnus thynnus (TT), Pagellus bogaraveo, and Dentex dentex (DD) from the Mediterranean Sea. The mean concentration of each element was calculated and compared to the provisional tolerable daily or weekly intake (PTWI) or to the established tolerable upper intake when possible. Specie-specific distribution was documented for the following chemical elements: aluminum (Al), potassium (K), cobalt (Co), molybdenum (Mo), silver (Ag), cadmium (Cd), tin (Sn), and thorium (Th). For the elements without regulated maximum dietary limits, iron (Fe) was highest in TT, while Th was significantly predominant in DD. Several metals were found, often simultaneously, in quantities above the acceptable levels. Specifically, the median concentrations of mercury (Hg) and Cd in the pooled species were significantly higher than their relative PTWI. Significant differences among species were reported for selenium (Se), inorganic arsenic (As), nickel (Ni), and zinc (Zn). Other elements [Al, chromium (Cr), copper (Cu), Sn, lead (Pb), and manganese (Mn)] were found to be at or below the corresponding acceptable levels. The maximum safe consumption calculated for Hg leads to advising a limited recommended weekly intake for all the tested Mediterranean Sea fish species.
