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
Background and Aim: Hospital effluents are a major source of environmental contaminants, harboring pathogenic bacteria, toxic trace metals, and high organic loads. This study aimed to evaluate the bacteriological and physicochemical profiles of wastewater discharged from three coastal hospitals in Oran, Algeria, and to assess the associated public and livestock health risks under the One Health approach. Materials and Methods: A cross-sectional study was conducted from January 2023 to February 2024, involving monthly sampling at three hospitals and one drainage collector. Twenty-six composite samples were collected at three peak daily intervals. Bacteriological analysis targeted Results: All effluents contained pathogenic bacteria, with peak concentrations of Conclusion: Untreated hospital wastewater in Oran poses a serious threat to public and environmental health. The presence of multidrug-resistant bacteria and toxic metals highlights the urgent need for dedicated hospital wastewater treatment infrastructure. Grazing livestock and marine ecosystems exposed to these effluents are at risk of bioaccumulation and infection. Regulatory enforcement, routine monitoring, and the implementation of sustainable green hospital plans are essential to safeguard health under the One Health paradigm.
