  1. Multivariate analyses (linear mixed models) were performed to compare the difference of Ab mean level between both groups taking into account the Ab measurements at 6, 12, 15 and 18 months of age
  2. Models were adjusted by age and environmental risk. Ab level from CAIG was considered as the reference in the model
  3. Significant p values (p < 0.05) are mentioned in italics
  4. Coef.: coefficient, Coef. > 0: indicate a higher level of Ab from 6 to 18 months of age in CAIG group compared to NCIG group, CI: confidence interval
  5. aERE represent environmental risk of exposure attributed quarterly for each infant included in the cohort
