Baseline characteristics by allocation group (n = 7775).
<p>Values are absolute numbers (percentages) for categorical variables. *Tested for differences in characteristics in intervention and control group using multinomial regression adjusted for randomisation stratum. Characteristics established using postal questionnaires during pregnancy included: <i>smoking during pregnancy</i> (yes, no), <i>maternal atopy</i> (yes, no), <i>maternal ethnicity</i> (Dutch, non-Western, other-Western) and <i>maternal educational level</i>. The Dutch Standard Classification of Education was used to categorise women’s self-reported highest education qualification <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0090982#pone.0090982-Statistics1" target="_blank">[21]</a>: low (less than 4 years of high school), middle (college), and high (Bachelor’s degree, Master’s degree). Data on net household income were available at the 2<sup>nd</sup> year of life. <i>Birth weight</i> (grams) and <i>gestational age at birth</i> (weeks) were obtained from medical records. Postnatal factors were established using questionnaires and included: <i>breastfeeding ever</i> at age 0–6 months (yes, no); <i>keeping pets</i> (yes, no) at the 1<sup>st</sup> year of life; <i>ETS exposure</i> at home (yes, no) measured at age 0–6 months; <i>respiratory tract infections</i> (yes, no) <i>and wheezing</i> (yes, no) at the 1<sup>st</sup> year of life.</p

Prevalence of ETS exposure at home of intervention and control (usual care) group by child’s age (Intention-to-treat analysis).
<p>ETS exposure at home was defined based on the question ‘Do people smoke occasionally at home?’. Values are percentages and were tested for differences in characteristics in intervention and control group using logistic regression analyses. Population for analysis (N) and <i>P</i> values: Prenatal (N = 5598): p>0.05, 6 months (N = 4233): p>0.05, age 2 years (N = 5290): p = 0.02, age 3 years (N = 4894): p = 0.004, age 6 years (N = 4604): p>0.05.</p
