[68] Adjusted for individual-level characteristics (gender, age, race, Hispanic ethnicity, economic status, smoking status, exposure to second-hand smoke at home, and use of a gas stove more than once per month) and school-level characteristics (rural locale, indoor air quality, and reports of other non-livestock industries nearby).

[62] Adjusted for age (5 categories), sex, active and passive smoke exposure, level of education, number of siblings, parental allergies.
