Fig 1 Smoothed plots showing adjusted prevalence of current asthma by A alternata antigen concentration for the house index and each sampling location. The estimated prevalence is adjusted for age, sex, race, education, smoking, and survey season.

Fig 2 Adjusted ORs and 95% CIs for the association between current asthma and A alternata antigen concentration in the household (continuous variable). The house index (the mean of the site-specific concentrations) and site-specific ORs correspond to a 2-fold increase in Alternaria concentration adjusting for age, sex, race, education, smoking, and survey season.
