Assessment and management of arsenic contamination in groundwater from Sanso, Ghana: Health risk implications, source identification, adsorption and immobilization for safe disposal.

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
Arsenic contamination in groundwater poses global health risks, but safe removal and disposal remain a significant concern for groundwater owners in developing countries. This study aimed to evaluate the health risks, sources, and concentration of arsenic species in groundwater from Sanso, Ghana, and further synthesize and characterize magnetic activated carbon (Fe-CAC) for arsenic removal, and solidify and stabilize the arsenic loaded onto Fe-CAC using cement, nickel oxide, and eggshell waste (AFCNE). Groundwater samples were collected from the Sanso community in Ghana. Arsenic speciation was determined using standard analytical methods and a flame atomic absorption spectrophotometer. Scanning electron microscopy, X-ray diffraction analysis, and Fourier transform infrared spectroscopy analysis were used to characterize the materials. The findings revealed that mean concentrations of total arsenic (15.463 μg/L) and arsenite (13.645 μg/L) did not conform to the WHO guideline value of 10 μg/L. The multivariate analysis revealed impacts of illegal mining activities, geological influences, and geochemical conditions strongly influencing arsenic enrichment and transport in aquifers. Children showed a higher chronic daily exposure to arsenic than adults, with oral exposure being significantly higher than dermal exposure. The cumulative carcinogenic and non-carcinogenic risk exceeded 10
