Table VII.

Genera (or lowest identifiable taxonomic level) identified as significantly different (FDR <.05) between breastfed and formula-fed infants, after adjustment for age, mode of delivery, maternal diet, whether the child was on solid foods at the time of stool collection, study treatment and maternal education, stratified by child race/ethnicity

Results shown for negative binomial regression analyses. β-coefficient is reflects the average difference in relative abundance between the breastfed and formula-fed groups after covariate adjustment.

^*Formula fed is reference group.

^†Taxa identified as significantly different in models without maternal education included as a covariate are displayed in Table III and included here for comparison.
