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
Polymerization-based wastewater treatment offers reduced oxidant demand and product recovery, yet practical application is hindered by catalyst fouling and unselective reactions due to single-site competition. Here, we report a readily synthesized and scalable ZnO/CuO catalyst featuring dual functional sites that decouple pollutant and oxidant activation. Zn sites preferentially adsorb/activate organics, whereas Cu sites predominantly activate the oxidant. This site differentiation programs two pathway regimes governed by pollutant electronic structure: electron-transfer-mediated polymerization for electron-rich substrates and radical-induced mineralization for electron-deficient substrates. Importantly, radicals generated during mineralization depolymerize the accumulated foulant layer in situ, effecting autonomous catalyst regeneration with a 2.5-fold performance recovery and reduced external regeneration demand. Process performance is validated in a 200 L self-circulating reactor, maintaining 98% removal efficiency for both pollutant classes over ten cycles. Toxicological profiling across multiple biological models, supported by metabolomics, confirmed effective detoxification of multi-pollutant wastewater, including restoration of normal metabolic function in zebrafish (e.g., lipid and glutathione metabolism). This study establishes a dual-site cooperative catalysis framework that leverages intrinsic wastewater chemistry for self-regeneration, showcasing a complete trajectory from atomic-scale design to reactor-scale implementation.
