On the Development of Innovative Column Internals for Nitrogen Recovery from Agricultural Waste.
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
Using agricultural waste as fertilizer results in contamination of groundwater, leading to environmental and health risks. A partial removal of ammonia is necessary before the waste application on fields, which can be realized via an air-stripping process. However, conventional column internals for air stripping are prone to clogging because of the high solid loads of the liquid waste. This was an impetus for the development of an innovative separator with new types of internal structures based on inclined plates. A numerical model and an experimental setup were established in our previous work and used to investigate the plates. In the present study, first, the initial packing concept was evaluated, showing promising results. Subsequently, the packing was optimized toward increasing the gas-liquid interfacial area, using both experimental and simulation-based approaches. The optimized internals prevent clogging, allowing sustainable continuous use of the column and making air stripping a more viable option for removing ammonia from liquid agricultural waste.
