1 · What the graph read from it

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.

2 · The registry

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 "School MicroBE" initiative explores how the built environment impacts microbial communities in school-aged children by examining temporal dynamics and shifts in nasopharyngeal and oral microbiomes. This longitudinal study involved 119 children aged 4 to 13 at a public school, with nasopharyngeal and oral samples collected in autumn, winter, and spring of 2023. Using 16S rRNA gene sequencing, we assessed microbial composition through alpha and beta diversity analyses, characterized microbial assemblages, and evaluated the relative abundance of key taxa. Significant seasonal variations were observed, with an increase in alpha diversity from autumn to spring in nasopharyngeal samples. Beta diversity analyses did not reveal distinct clustering patterns based on collection months. Hierarchical clustering identified four major microbiome groups with characteristic taxonomic distribution, and co-occurrence network analysis suggested both synergistic and competitive interactions among taxa. Longitudinal transition analysis between microbiome clusters revealed dynamic changes over time, providing a baseline of microbiome states in the tested children. These findings highlight the importance of microbial community shifts in the environment by providing direct measures on microbiome stability and diversity in children, providing insights into how microbial communities respond to environmental fluctuations, including potential pathogen exposures. Understanding these temporal changes will improve the development of targeted public health strategies to assess and manage potential infectious disease outbreaks and the emergence of antimicrobial resistance in school settings.IMPORTANCEThe "School MicroBE" initiative enhances our understanding of pediatric microbiome dynamics by revealing temporal and compositional shifts, thus establishing basal studies on a sentinel school contributing to the understanding of pediatric microbiome and its associated health issues.
