Table E1: Associations between early-onset AD (≤ 1 year) and late-onset AD (> 1 year) and allergic sensitization at 6 and 12 years. AD is either defined as a dichotomous variable (yes/no) or a continuous variable expressed as a severity score (SCORAD) for AD. The GEE§ model computes the overall aOR for allergic sensitization using compiled data from both time points. Analyses are adjusted for sex, older siblings, maternal allergic rhinitis, paternal allergic rhinitis, breastfeeding and smoking during 3rd trimester.
