DDT and Its Metabolites in Ethiopian Aquatic Ecosystems: Environmental and Health Implications.
Review in Environmental health insights, 2024. 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
Background: Despite its significant application, DDT and its metabolites pose a potential threat to the environment. Therefore, data on environmental and health concerns must thus be investigated. Objective: The objective of this study was to assess the environmental and human health risks posed by DDT and its metabolites in Ethiopian surface waters. Methods: The total amount of DDT and its metabolites consumed as a sum (∑DDT) is calculated by considering their equivalent toxicity. To calculate the human risk from drinking contaminated water, the maximum concentrations in all of Ethiopia's surface waterways were pooled. The average concentration values were added to calculate the human risk from consuming fish contaminated with ∑DDT. Similarly, ∑DDT residues in water can be used to predict the potential environmental risk. Results: A higher level of ∑DDT in surface water was detected in Gilgel Gibe I hydroelectric dam reservoir and its tributaries with an average concentration of 640 ng/l. There is no health risk associated with drinking these surface waters because the concentrations of ∑DDT were below the WHO's recommended level. In fish samples, Conclusion: The prevalence of ∑DDT would link to both historical pollution and their current application in vector control. Ecosystems are frequently exposed to chemical mixes later in life; thus, rather than focusing on the ideal case of exposure to a single toxin, future studies can examine the mixture toxicity of numerous organic contaminants.
