Associations of intelligence quotient (IQ) scores with mothers’ and childrenʼs urinary phthalate concentrations by linear mixed model (na = 251).

aThe number of observations (n) represents the sum of all subjects studied at both birth and 1st follow-up visit at 2 years of age, and at least once at 5, 8, or 11 year follow-up.bAdjusted for gender, HOME score, birth weight, maternal education, lactation, and children’s age.cMaternal and children’s levels of urinary phthalate were both independent variables to predict IQ scores in the model.dΣMEHP = MEHP + MEHHP + MEOHP.Associations of intelligence quotient (IQ) scores with mothers’ and childrenʼs urinary phthalate concentrations by linear mixed model (na = 251).
