  • All models for the logarithm of allergen sIgE levels were Tobit models based on truncation of data at the lower level of detection for sIgE. Levels of sIgE to allergen were expressed on a logarithmic scale. The model included demographic and SES variables as described for the other tables. The model also included potential confounders considered on the basis of literature reports (maternal atopy, cesarean section, firstborn status, and exclusive breastfeeding), irrespective of significance, and variables found to be potential confounders of the association of race with any food sensitization in our data (prenatal smoke exposure and maternal postnatal smoking). Ancestry was expressed in 10% increments.
