CI, Confidence interval.
ORs and 95% CIs are from logistic regression.
Bold indicates statistical significance (P < .05).
∗
Numbers apply to both analyses, unless 2 figures are presented, whereupon they apply to unadjusted and multivariable analysis, respectively.
†
Percentages apply to both analyses, unless 2 figures are presented, whereupon they apply to unadjusted and multivariable analysis, respectively.
‡
Analyses are adjusted for parental history of asthma, history of atopic dermatitis, siblings, and study center.
