^{^a}

Model 1 includes individual exposure and response variables.

^{^b}

Model 2 includes the individual exposures and response and demographic covariates (age, sex, asthma diagnosis, current employment in agriculture, lives with someone currently employed in agriculture).

^{^c}

Model 3 is exposure and response plus demographic covariates, and meteorological covariates (temperature and relative humidity).

^{^d}

All model estimates are scaled by the IQR of the relevant exposure, with the exception of total DE, which had an IQR of 0.

^{^e}

January n = 74.

^{^f}

June n = 75.
