Paper-Based Microfluidics Platform for Enhanced On-Site Electrochemical Detection of Manganese in Water.
Article in ACS omega, 2026. 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
Manganese pollution in water has severe toxic effects on biological organisms, including humans. Early detection is crucial to apply timely corrective measures and prevent irreversible consequences. Standard monitoring methods are expensive, time-consuming, and difficult to implement in resource-limited settings, leading to inefficient pollution remediation. The low cost and small size of screen-printed electrodes make them well-suited for on-site analysis but require flow conditions for sensitive results, making them difficult to implement in real-world scenarios. To address this challenge, we present the use of paper microfluidics in combination with screen-printed carbon electrodes for the electrochemical detection of manganese in water. Capillary-driven flow using paper microfluidics provided a practical fluid delivery method for on-site electroanalysis, which was compared to conventional flow methods, i.e., batch setups and flow cells, to demonstrate fitness for purpose. The sensing platform showed a linear response to Mn-(II) up to 200 μg L
