Variables	Univariable analysis		Multivariable analysis
	Beta coefficient	p value	Beta coefficient	p value
Lead*	0.003	0.123	1.113	0.562
Mercury*	0.115	0.072	2.179	0.054
Chromium*	0.260	0.135	0.277	0.037

Multivariable analysis was performed after adjustment for maternal history of allergic diseases, maternal education level, exclusive breastfeeding during the first 6 months of life, and season of birth.

^*The values were log-transformed; ^†The levels were transformed to log_e(log_e(Cd×10)+10).
