Adjusted for age, age2, HLA-DR3/4, DQB1*0302, first-degree relative with T1D, sex, maternal education, maternal
age, and exposure to maternal cigarette smoke in utero.
The mean age at first exposure to any solid food is less than the means of its components because 13 children were introduced to cheese before any cereal.
P value < 0.05.
