  1. $ If not otherwise stated, the comparisons are dichotomous with the referent category being the low-odds group (aOR = 1), and the high-odds group data shown in the table.
  2. #Adjustments were made for gender, age, family history of allergic disease, asthma, length of breastfeeding, PVC-flooring material in the home, type of building, environmental tobacco smoke, and number of adults living with the child.
  3. ## Defined as eczema ever for at least 6 months, and current eczema in both 2000 and 2005.
