5-year average noise as covariate (n = 1029):	.0011 (−.0066, .0088)

^aPregnancy noise included as a covariate in the postnatal sample analyses, and postnatal noise included in the pregnancy sample analyses
^bIncluding only children who are part of both pregnancy and postnatal samples. Covariates included are road traffic noise, age, gender, household income, maternal education, urbanity, ethnicity, maternal alcohol consumption during pregnancy, maternal smoking during pregnancy, low birth weight (>=/<2500 g) and prematurity (>=/<259 days)
