  1. aAssociations are presented as mean difference in Rint per interquartile range increase in air pollution exposure (β) with 95% confidence intervals (CI). Adjusted for sex, age, height, weight, parental education, parental allergies, maternal smoking during pregnancy, smoking in the child’s home, mold/dampness in living room and/or child’s bedroom, pets in the child’s home, use of gas for cooking, unvented gas water heater, older siblings, Dutch nationality, season; average air pollution concentration (NO2 in models with long-term NO2 and NOx; PM10 in models with long-term PM2.5, PM10, and PMcoarse; black smoke in models with long-term PM2.5 absorbance), ambient temperature and relative humidity on the day of the Rint test
