For binary outcomes, the adjusted OR (95% CI) from logistic models is presented. For continuous outcomes, the regression coefficient (β, 95% CI) from linear regression models is presented and reflects the adjusted difference in score (i.e. score for aberrant birthweight – score for AGA).

None of the comparisons were statistically significant except for these ones marked with (#) which had a p<0.05
