NC1, Nutrition Cohort 1; NC2, Nutrition Cohort 2; del=one base-pair deletion; BSID-II, Bayley Scales of Infant Development II; MDI, Mental Developmental Index; PDI, psychomotor developmental index.
β Coefficients, 95% CI and P values presented are from linear regression models adjusted for child sex, maternal age at delivery, presence of two parents in the household, socioeconomic status, and birth weight (for NC1) or child age at testing (NC2). P-values are from the 2 df tests comparing the 3 levels of each genotype.
rs3834458 is FADS1-FADS2 intergenic (NCBI).
Reference genotype.
