Previous domestic ETS (age 4) 0.36 0.015 0.34 0.032

a

Linear regression models with log-transformed FeNO as the dependent variable and the independent variables sex, maternal asthma, previous domestic environmental tobacco smoke (ETS), current domestic ETS, ambient NO and either log-transformed total IgE (model 1) or seroatopy (model 2).

b

Seroatopy was defined as specific IgE ≥0.35 IU/ml to at least one of the allergens tested (Dermatophagoides farinae, German cockroach, mouse, and cat)
