  1. All data presented as median (Q1, Q3), N/A not available (SDS length and SDS BMI could not be computed before term)
  2. Abbreviations: Body mass index (BMI), Standard deviation score (SDS)
  3. *Significantly different between the two cohorts (p < 0.05; Mann-Whitney-Test)
  4. Child’s routine developmental screening examinations: S1: 6 to 7 months after birth, S2: 10 to 12 months after birth, S3: 21 to 24 months after birth, S4: 46–48 months after birth, S5: 60–64 months after birth
