Notes regarding interpretation of presented column values:
These values reflect the raw % of individuals in each subpopulation who report outgrowing a convincing milk allergy. For example, 0.4% of Non-Hispanic Black Americans have outgrown a convincing milk allergy compared to 0.7% of Non-Hispanic White Americans.
These values reflect the relative distribution of each characteristic used to define the above subpopulations among individuals who report outgrowing a convincing milk allergy. For example: among US individuals who have outgrown a convincing milk allergy, 54.1% are female and 26.2% have asthma.
These values reflect the raw difference in the relative distribution of each characteristic between individuals who report outgrowing a convincing milk allergy vs. individuals with a current convincing milk allergy (i.e. the values reported in Table 1. For example: among individuals who have outgrown a convincing milk allergy, Non-Hispanic White individuals are over-represented (by 15.6 percentage points) compared to the % of non-Hispanic White individuals with a current convincing milk allergy
