Toxic metals and metalloids in collagen supplements of fish and jellyfish origin: Risk assessment for daily intake.

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
Aim: We examined marine collagen supplements derived from fish and jellyfish for the presence of toxic metals and metalloids (Pb, Cd, Cr, Hg, and As). A risk assessment was also carried out by converting the obtained concentrations into average daily doses (ADDs) and comparing them with tolerable daily intakes (TDIs) to evaluate potential health risks associated with long-term consumption. Methods: The levels of Pb, Cd, Cr, and As in marine collagen samples were quantified using inductively coupled plasma mass spectrometry (ICP-MS). Mercury levels were analysed with a direct analyser. The study analysed various brands of marine collagen supplements from fish and jellyfish, ensuring compliance with EU regulatory limits. Results: Arsenic was the most abundant element detected, with mean values of 0.59 ± 0.28 mg/kg, followed by Pb (0.13 ± 0.02 mg/kg). Significant variability was observed between brands. Hg was detectable in only 12% of the samples. Marine collagen samples derived from jellyfish and
