Impact of maternal fecal microbiota on the early development of neonatal gut microbial community.
Article in Frontiers in pediatrics, 2026. 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
Background: Maternal gut microbiota may contribute to initial colonization of neonatal fecal microbiota, but how closely neonatal fecal communities in early life reflect maternal stool is unclear. Methods: We performed 16S rRNA gene sequencing on paired maternal fecal samples collected at delivery and neonatal fecal samples collected within the first week of life from 21 mothers and 25 neonates respectively. Alpha and beta diversity and pairwise taxonomic overlap were assessed. Results: Maternal stool and early neonatal fecal samples shared a similar phylum-level profile dominated by Firmicutes. However, neonatal fecal samples had significantly lower alpha diversity and clustered separately from maternal samples, indicating a distinct community structure. Within-pair overlap supported partial maternal contribution, but many taxa in early neonatal fecal samples were not detected in maternal stool, suggesting additional perinatal or postnatal sources. Conclusion: Early neonatal fecal samples represent a low-diversity pioneer community rather than a direct replica of the maternal gut microbiota, refining models of early-life microbial transmission.
