Maternal obesity alters human milk oligosaccharides content and correlates with early acquisition of late colonizers in the neonatal gut microbiome.

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
Metabolic and immune development in neonates are shaped by the succession of the gut microbiome. Maternal obesity can perturb this process by altering interactions of human milk bioactive elements, including oligosaccharides (HMOs), microbial populations, and metabolites. We conducted a longitudinal study of Mexican mother-infant dyads to examine maternal BMI-associated variations in HMOs and infant fecal microbiota. Breastmilk samples from 97 mothers were collected at 48 h, one month, and three months postpartum. We used targeted and untargeted metabolomics to profile breastmilk samples, while shotgun metagenomics was used to analyze infant fecal microbiome composition in a subset of samples. Mothers with obesity showed decreased concentration of key HMOs shortly after birth, correlating with an altered succession of their infant's gut microbiota. This included reduced early colonizers (Enterobacteriaceae) and increased abundance of intermediate and late colonizers (
