longitudinal — not resolvedmother–infant — not resolved

Schedule stated by the source: “Mothers sampled throughout pregnancy; infants sampled during first year of life; head circumference assessed at month 12”; stated follow-up 12 mo.

264 mother–baby dyads (per description); mothers sampled in pregnancy, infants in year 1; no per-sample dyad or role field in the archive.

Archive description

Utilizing the large-scale longitudinal fecal samples from 264 mother-baby dyads, we characterized the gut microbiome trajectory of the mothers during pregnancy and infants during the 1st year life.
