Strata	Sensitization (≥ 1 positive allergen-specific IgE test)	n	Cord blood IgE (kU/L) Geometric Mean (95% CI)	OR^* (95% CI) p-value
All	- Yes	312	0.24 (0.21, 0.27)	1.18 (1.02, 1.37)
All	- No	253	0.19 (0.17, 0.22)	p=0.031

Pet exposure during first year of life	- Yes	136	0.21 (0.18, 0.26)	0.94 (0.76, 1.18)
Pet exposure during first year of life	- No	115	0.23 (0.18, 0.28)	p=0.61

No pet exposure during first year of life	- Yes	176	0.26 (0.22, 0.31)	1.43 (1.16, 1.77)
