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
Environmental stressors can influence the gut microbiota of wild ruminants, yet their effects in free-ranging populations remain poorly understood. This study examined associations between physiological stress and gut microbiota composition in free-ranging European roe deer (Capreolus capreolus) from agricultural landscapes in central Poland. Fecal samples from 54 legally hunted individuals were analyzed for cortisol metabolite concentrations and bacterial community composition using 16S rRNA gene sequencing. Cortisol metabolite levels ranged from 17.9 to 371.4 ng ml⁻¹, allowing classification into low- and high-stress groups. Alpha diversity metrics did not differ between groups, but beta diversity analyses revealed significant differences in microbial community structure linked to stress. Stress remained a significant predictor of microbiota composition even after adjusting for confounding variables such as area and season, with its effect varying by context. Ratios of Christensenellaceae to Rikenellaceae, Bacteroidaceae and Prevotellaceae were significantly elevated in the high-stress group, indicating potential as microbial biomarkers of physiological stress. Additionally, Barnesiellaceae and Succinivibrionaceae (families involved in immune modulation and fermentation) were depleted under higher stress conditions. These findings highlight the role of gut microbiota in responses to environmental stressors and suggest that microbial signatures could serve as biomarkers for assessing the impact of agriculture on wildlife health and ecosystem stability.
