Bioaccumulation of Trace Elements in Fish From Lake Kivu and Its Potential Risk to Consumers in Rwanda.
Article in Food science & nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Lake Kivu, located between Rwanda and the Democratic Republic of the Congo, is subject to trace element contamination primarily due to the geological composition of its bedrock, watershed soils, and anthropogenic activities. In this study, we investigated the accumulation of trace elements in 13 fish species from Lake Kivu, with samples obtained from fishermen in Rubavu, Karongi, and Rusizi. The fish samples were digested and analyzed for selected trace element concentrations using atomic absorption spectrophotometry (AAS). The concentrations of trace elements in the fish ranged from 0.07 to 2.53 mg/kg for mercury (Hg), 0.69 to 1.16 mg/kg for cadmium (Cd), 0.28 to 0.76 mg/kg for copper (Cu), 2.58 to 3.83 mg/kg for chromium (Cr), and 0.22 to 0.68 mg/kg for manganese (Mn). The highest bio-concentration factor (BCF) was observed for mercury.
