A Citizen-Science Study Documents Environmental Exposures and Asthma Prevalence in Two Communities

Table 3

Results of logistic regression models examining the association between ERMI values and self-reported current asthma. Odds ratios are presented for all variables included in the final models, which included the ERMI value (included as a linear term in the model), smoking inside the residence, and residence duration (in the unstratified model).
