^aEES = exposure elementary school; CES = control elementary school.

^bPEF = peak expiratory flow; FeNO = fractional exhaled nitric oxide.

^cOR = odds ratio; 95% CI = 95% confidence interval.

^dModel = school (1 = EES, 0 = CES), age, race, environmental tobacco smoke, time spent outdoors, median household income, total diesel pollution, and proximity to nearest major road.

^eSensitivity analysis included only subjects residing more than six months at their current address.
