Article in Biological trace element research, 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
The acceleration of global population growth will consequently result in a surge of demand for food. The cultivation of insects for human consumption represents a significant method of satisfying human nutritional requirements. The aim of this study is to analyze the concentration of selected metals, namely iron, zinc, lead, cadmium, and arsenic, in traditional food products and to compare them with the concentrations of these trace elements in food products containing house crickets. The samples of traditional food products (n = 27) and food products containing house crickets (n = 30) were classified to the food categories: flour, pasta, crisps, bars, chocolate, crisp bread, crackers, bread spreads, bread sticks, and dried snacks. The concentration of lead, cadmium, zinc, arsenic, and iron was determined through the use of inductively coupled plasma optical emission spectrometry (ICP-OES) and electrothermal atomic absorption spectrometry (ET-AAS). The number of scientific reports on the assessment of the health risk associated with dietary exposure to metals through the consumption of food containing edible insects is relatively limited. The results of the present study demonstrate that products containing house crickets exhibit higher concentrations of zinc, iron, and arsenic than traditional products (Mann-Whitney U test). The R-Spearman rank correlation test revealed a statistically significant correlation between the percentage content of house crickets in food products and the concentrations of zinc and iron. The results of the study indicate a positive correlation between the percentage of house crickets in food products and the concentration of metals.
