Heavy Metals in Foods Consumed by Copper Miners: A Health Risk Assessment.
Article in Food science & nutrition, 2025. 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
Due to the high occupational exposure of miners to heavy metals, the concentration of arsenic, cadmium, lead, copper, and zinc in raw and cooked foods consumed by mine workers and the risk assessment of the consumption of these foods were investigated. A total of 105 samples of raw and cooked foods and beverages were collected. Samples were oven-dried, digested with microwave-assisted nitric acid for the analysis of heavy metals using an ICP-OES. The health risk assessment was performed through hazard quotient (HQ) and hazard index (HI) calculations. The concentrations of all heavy metals measured in both raw foods and cooked foods were lower than the permissible limits as determined by FAO/WHO and Iranian national standards. The HQ and HI for all metals were less than one, signifying no health risk from dietary exposure. Heavy metal levels in food taken by miners fell within permissible limits, but periodic monitoring is necessary because of miners' occupational exposure to heavy metals.
