Results of children at the exposure elementary school (ES) experiencing adverse respiratory related health outcomes in contrast with the comparison elementary school (CS)

β regression coefficient, 95 % CI 95 % confidence interval, PEF peak expiratory flow, FeNO fractional exhaled nitric oxide, PEF−inh peak expiratory flow excluding subjects with parent-reported inhaler use, FeNO −inh fractional exhaled nitric oxide excluding subjects with parent-reported inhaler use

Model = school, age, gender, race, environmental tobacco smoke (ETS), time spent outdoors, medium household income, proximity to nearest major road, total diesel pollution

b

Sensitivity analysis included only subjects residing more than 6 months at their current address
