Description: Meta-analysis of all seven included studies for gut bacterial taxa with differential relative abundances between non-exclusively breastfed vs. exclusively breastfed infants ≤6 months of age.
Meta-analysis of five studies that included a non-breastfeeding group for gut bacterial taxa with trend in relative abundance across exclusive breastfeeding, non-exclusive breastfeeding and non-breastfeeding groups.
