a
Values are means ± standard deviations (SD), except for numbers or percentages of samples. The total number of values was 56. The total number of samples from secretor mothers was 43. The mode of delivery was vaginal for 100% of the mothers, and the mode of feeding was breastfeeding for 100% of the infants. Maternal secretor status was found to affect the gut microbiota composition of breast-fed infants. We examined the maternal secretor status and eliminated samples of nonsecretor mothers (n = 13) and their infants (Table S1). The remaining secretors were grouped into the G and A groups according to their Fut8 gene status (SNP at rs10483776).
b
BMI, body mass index.
