1Defined as parental report of physician-diagnosed eczema at or before 6 months of age

2There was no difference in microbial diversity when comparing delivery modes regardless of eczema status (p > 0.90)

3Mann-Whitney U-test p-value

4Number of denaturating gradient gel electrophoresis (DGGE) bands in each sample

5Shannon diversity index (H') calculated using the relative intensity of all bands within each sample
