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
Perfluorooctanoic acid (PFOA) is a persistent environmental contaminant with the potential to disrupt soil-plant systems. This study investigated the impacts of PFOA on soil microbial viability and community composition under aerobic and anaerobic conditions, to understand microbial resilience and adaptability to pollutant stress. Soil samples from an uncontaminated agricultural field (2.26 ng/g) were amended with varying PFOA concentrations (0, 40, 60, 80, and 100 mg/kg) and incubated under controlled conditions for 7 days. Microbial viability was assessed through colony-forming unit (cfu) counts, while community composition was characterized via 16S rRNA gene sequencing. Results showed a significant decline (8-79%) in microbial viability at higher PFOA concentrations across both environments, with anaerobic soils exhibiting greater sensitivity, underscoring the role of oxygen availability in microbial pollutant tolerance. Taxonomic analysis revealed concentration-dependent shifts, with Actinobacteria and Proteobacteria dominating under aerobic conditions, and Chloroflexi, Bacteroidetes, and Acidobacteria prevailing under anaerobic conditions. The novelty of this study lies in its systematic comparison of microbial community responses and adaptive mechanisms under both aerobic and anaerobic soil conditions, providing critical insights into the differential impacts of PFOA that have previously not been explored.The findings highlight the ecological significance of resilient taxa in sustaining carbon and nutrient turnover in contaminated soils.
