Results are shown as Z-scores, calculated by dividing the individual values by the corresponding baseline SD in the AGA group. For birthweight (BW) the Z-score was calculated using the corresponding SD in the general population. Plots represent means ± 95% CI. **p ≤ 0.01 and ***p ≤ 0.001 for differences between groups by Student t-test.
