Useful biomarkers for assessing the adverse health effects of PCBs in allergic children: pediatric molecular epidemiology

Table 5 Relationships between the total maternal/cord blood PCB concentration and ST volume or the placental concentration of PlGF or SFlt-1 [20]

	ST^b			PlGF^a,b			sFlt-1^a,b
	Coefficient	SE	P value	Coefficient	SE	P value	Coefficient	SE	P value
Total PCB (pg/g-fat) in maternal blood	−1.77	0.93	0.076	2.35	0.90	0.019	0.10	1.31	0.943
Total PCB (pg/g-fat) in cord blood	−1.02	1.61	0.534	3.89	0.95	0.001	−1.03	2.01	0.615

P values were obtained using multivariate regression models
Placental weight, the PlGF concentration, and the sFlt concentration were included as covariates
Coefficient: regression coefficient
SE standard error
^a N = 21
^b z score transformation was performed
