Some mothers had a record of more than one disease.

Separate models were performed for each maternal atopic disease and were adjusted for year of birth. The reference groups consisted of mothers without each atopic disease.

Adjusted for year of birth, other maternal diseases in table, maternal age, single mother at birth, parity, and seasonality.
