Data are given as mean ± SD or median Q1; Q3. P correspond to ANOVA or Kruskal–Wallis test, as appropriate. Significant differences in post hoc tests (Dunnet or Mann–Whitney U) between SGA or LGA and AGA are indicated with * and **, corresponding to two-sided significance levels of < 0.05 and < 0.01, respectively. The significance level of Mann–Whitney U test is Bonferroni-corrected for two group comparisons. AGA appropriate for gestational age; LGA large for gestational age: SGA small for gestational age
