AIC, Akaike's information criterion; MSE, mean squared error.
Birth order and total siblings adjusted one for each other.
Birth order and younger siblings adjusted for confounding variables: family income, maternal education, presence of the father, maternal skin colour, maternal age at birth, maternal height, gestational weight gain, pregnancy smoking consumption, pregnancy alcohol consumption, gestational systemic hypertension and gestational diabetes.
