^{^a}

For some variables, the sum of categories was not equal to the total due to missing data.

^{^b}

Mean difference for continuous outcome per month older age at egg introduction adjusted for maternal sociodemographic characteristics (e.g., age, education level, family income, race/ethnicity, and marital status), health behaviours/status during pregnancy (e.g., preconception BMI, gestational weight gain, and gestational duration), child sex, the corresponding growth measurement at birth, and infant age at introduction of other complementary foods.
