^aTotal antioxidant capacity intake (μmol Trolox equivalents/day) as measured with oxygen radical absorbance capacity assay, energy‐adjusted to 1900 kcal/day.

^bAdjusted for sex, parental history of allergic disease, early maternal smoking and parental socio‐economic status if the factor was not the one stratified for.

^cParental smoking at 8 years of age.

^dNO_x exposure at 8 years of age, divided in tertiles.

n/N, number of new onset cases/total number of children; Ref, reference group; OR, odds ratio obtained from multivariate logistic regression model; 95% CI, 95% confidence interval; LRT, likelihood ratio test.Bold text indicates a statistically significant difference with a p‐value less than 0.05
