  1. * p < 0.05. Difference between exposed and unexposed (boys and girls together) tested with Fisher's exact test for categorical variables and Mann-Whitney U-test for continuous variables.
  2. †Values are presented as n (%) (categorical variables) or median (5; 95 percentiles) (continuous variables). Information from new controls was collected from birth records and questionnaire at school age (smoking and alcohol).
  3. ‡ Information on alcohol intake (yes/no) (n = 174).
  4. § Information on breastfeeding until 3 months (mainly or exclusively/little or no), (n = 200: 13 unexposed girls, 21 unexposed boys).
