Table 3. Effect of secretor status on Prevotella abundance.

				Median Prevotella Abundance by Secretor Status
	Sample size(secretor)	p	pFDR	S	N-S
Child Secretor Status	28 (20 S)	< 0.001	<0.001	0	3
Mother’s Secretor Status	17 (11 S)	< 0.001	<0.001	0	4
Mother’s Secretor Status–ABF	14(10 S)	< 0.001	<0.001	0	4055.5
Mother’s Secretor Status–EBF	11 (8 S)	< 0.001	<0.001	0	8106

Results of DESeq2 analysis (total sample size (number of secretors), DeSeq2 calculated p value, Benjamini-Hochberg adjusted p values (pFDR) and median absolute count of Prevotella) of association of Prevotella abundance by child secretor status, mother secretor status, mother secretor status—ABF (Any Breast-Feeding) subgroup, with the 2 formula-fed children excluded, and mother secretor status—EBF (Exclusively Breast-Fed) sub-group, containing only children who had been exclusively breast-fed for at least 4 months.
