Tracing of streptococcal strains from infant stools across human body sites links site-specific prevalence to adhesins.
Article in Applied and environmental microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Streptococci colonize various human body sites, both as commensals and as pathogens. They are early gut colonizers, but we lack strain-level information about the origin and persistence of streptococci in the non-diseased gut. To gain a greater insight into commensal streptococci in the infant gut and their presence in other body habitats, we analyzed samples from mother-infant pairs collected from multiple body sites (stool, oral cavity, vagina, breast milk). We performed whole-metagenome sequencing and isolated streptococci from 100 infant stool samples (collected at 10 days of age). To trace the streptococci at the strain level, we designed selective quantitative PCR (qPCR) primers for seven streptococcal strains, which were then used to screen the corresponding samples from the other body sites of the infants and their mothers. We found that two of the strains investigated, one
