Bidirectional relations between the maternal and infant gut microbiome and behavior.
Article in Pediatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundAn infant's mother is one of the first sources of neonatal microbial colonization, and infant-maternal dyad microbial variations have been linked to childhood behavioral traits and mental health outcomes. However, how the gut microbiome influences mental health, including potential bidirectional relations between mother and child, remains poorly understood.
methodUsing metagenomic sequencing and behavioral questionnaires, we examined within-person and between-person (mother-infant dyad) associations between the gut microbiota and behavior across the first year of postnatal life (N = 121 dyads; N = 514 stool samples).
resultsThere were rapid changes in taxa diversity and gut microbiota composition for infants, whereas the maternal microbiome remains relatively constant. Gut microbes and functional terms (e.g., antibiotic resistance genes and virulence factors) were associated with infant temperament but not maternal depression symptoms. Whereas maternal depression was not associated with any maternal taxa or functional terms.
conclusionsOur findings provide evidence for complex within- and between-person relations between maternal and infant gut microbiomes and behavioral traits. IMPACT: How the gut microbiome influences maternal mental health and infant behavior remains poorly understood. We measured mothers' and infants' gut microbiota composition and behavior across the first year of the infant's life. Individual taxa from the infant, but not the maternal, gut were associated with infant behavioral temperament. Our findings provide evidence for complex bidirectional gut-behavior associations between mothers and infants.
