Association between the negative domains score and log cord blood IgE stratified by low (< 0.20 μg/g) versus (≥0.20 μg/g) high prenatal dust mite allergen exposure and maternal atopic status^†

	N	High Dust Mite	Low Dust Mite	Interaction β estimate (p-value)
		β estimate for log cord IgE (p-value)	β estimate for log cord IgE (p-value)
All Mothers	380	0.10 (0.01)	0.12 (0.07)	−0.01 (0.85)
Atopic‡ Mothers	127	0.21 (0.002)	−0.04 (0.73)	0.25 (0.06)
Non-atopic Mothers	253	−0.01 (0.87)	0.17 (0.03)	−0.17 (0.05)
