Gut microbiota dynamics in SAMP8 mice: insights from machine learning and longitudinal analysis.
Article in Microbiology spectrum, 2025. 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
The gut microbiota plays a crucial role in maintaining host health, and its composition is significantly influenced by aging. The SAMP8 mouse model, known for its accelerated aging process, is widely used to study age-related changes. However, comprehensive longitudinal studies on gut microbiota dynamics in SAMP8 mice remain limited. We analyzed microbiota profiles of SAMP8 mice at 1, 3, 7, and 10 months ( IMPORTANCE: Aging is associated with profound changes in microbial composition, yet the precise trajectories and key microbial signatures of aging remain incompletely understood. This study provides a comprehensive analysis of gut microbiota dynamics in aging SAMP8 mice. By identifying significant shifts in microbial diversity, composition, and aging-related trajectories, our findings highlight the progressive restructuring of gut microbiota with age. Understanding these changes is critical for uncovering potential microbial biomarkers of aging, which could serve as diagnostic tools or therapeutic targets to promote healthy aging. Notably, we demonstrate that some key taxa, such as
