^*Prevalence differences between with and without are significant at p<.05

^aAll percentages were weighted using NHANES survey weights

^bSubsamples for monitored PM_2.5, O₃, NO₂, and PM₁₀ linked to NHANES participants

^cSubsamples for PM_2.5, O₃, and NO₂ linked to NHANES participants based on CMAQ data

^dAny=Detectable specific IgE to indoor, outdoor, or food allergens

^eInhalant= Detectable specific IgE to indoor or outdoor allergens

^fOutdoor= Detectable specific IgE to Alternaria alternata, Asperigillus fumigatus, Bermuda grass, birch, oak, ragweed, Russian thistle, or rye grass

^gIndoor= Detectable specific IgE to cat dander, cockroach, dog dander, dust mite (Dermataphagoides farinae and Dermatophagoides pteronyssinus), mouse proteins, rat urine proteins
