Trace Elements in Breakfast Cereals and Exposure Assessment in Moroccan Population: Case of Lead and Cadmium.
Article in Biological trace element research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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 role of breakfast cereals in a balanced diet has been recognized for many years. Such foods should be safe and not contain toxic substances, especially trace elements. Among these elements, lead (Pb) and cadmium (Cd) are two important inorganic food contaminants. In this study, we assessed the contamination levels of breakfast cereal samples available in Morocco with Pb and Cd. For this, a total of sixty-two (n = 62) samples of breakfast cereals purchased in different markets in the country were surveyed for their Pb and Cd contents by using atomic absorption spectrophotometer (GF-AAS) after total mineralization of samples. Results showed that out of 62 total samples, 47 samples (75.8%) were contaminated with Pb concentrations in the range of 0.016-1.057 μg/g. The remaining samples (24.2%) were under the detection limit (LOD) of Pb. In the case of Cd, 41 samples (66.1%) were contaminated with Cd levels that ranged between 0.011 and 0.123 μg/g. In the present study, four samples (6.45%) of breakfast cereals are above the maximum limit (0.2 μg/g) set by the European Commission Regulation No 1881/2006 for Pb in cereals. However, for the Cd, only one sample exceeded the maximum limit set for this element (0.1 μg/g). The levels compare well with those reported worldwide for similar foodstuffs. The estimation of the provisional weekly intakes of the two elements (Pb and Cd) showed that the risks of development of toxicological effects through breakfast cereals are very low. However, it is important that the long-term exposure to these elements be kept to minimum. This is the first study on the co-occurrence of the two trace elements (Pb and Cd) in breakfast cereal samples commercialized in Morocco.
