Figure 2From: Maternal exposure to air pollution before and during pregnancy related to changes in newborn's cord blood lymphocyte subpopulations. The EDEN study cohort Associations between lymphocytes percentages and benzene exposure. Relationships between lymphocyte subset percentages in cord blood of newborns and benzene exposure in the sub-group of 56 non-smoking mother-newborn pairs with BETX (Benzene, Ethylbenzene, Toluene, Xylenes) assessment. β (95% CI): adjusted regression coefficient and 95% confidence interval for mother's age and body mass index, maternal history of allergy, passive smoking, perinatal infections, mode of delivery, newborn's sex and weight, preterm birth and season of birth). β corresponds to the change in lymphocyte percentages (log-transformed for natural killer cells) for each increase in one in log-transformed benzene exposure (n = 56). * p = 0.05.Back to article page
