Immune markers in newborns and developmental delay through age three years (n=3038).

Legend: Lines denote adjusted odds ratios (95%confience intervals), respectively. Models adjusted for a child’s sex, maternal age, maternal educational levels, maternal race, maternal history of smoking in pregnancy and drinking alcohol, maternal pre-pregnancy body mass index, having private insurance, parity, history of infertility treatment, plurality, mode of delivery, gestational age, and birthweight. Odds ratios refer to the effect estimates per standard deviation change in levels of immune marker (in logarithmic scale or square-root). Developmental delay was defined if children had scores two standard deviations below the mean for their age through age three years based on the Ages and Stages Questionnaire scores.
