Table 4.

Results of the PERMANOVA test using both delivery mode and antibiotic exposure.

First sequential test	Bray–Curtis		Jaccard		Second sequential test	Bray–Curtis		Jaccard
	R2	p-value	R2	p-value		R2	p-value	R2	p-value
Maternal antibiotic exposure	0.044	0.001	0.034	0.001	Delivery mode	0.5	0.002	0.037	0.001
Delivery mode	0.028	0.01	0.022	0.014	Maternal antibiotic exposure	0.022	0.025	0.019	0.022

Both sequential tests were adjusted for DNA extraction batch as first covariate. In the first test, maternal antibiotic exposure was added as covariate prior to delivery mode, while in the second test their order was inverted.

Significant values are in bold.
