  1. All data presented as median (Q1, Q3).
  2. *Significantly different between the two cohorts (p < 0.05 by Mann-Whitney-Test)
  3. N/A not available (SDS for length and for BMI could not be computed at birth before term).
  4. Abbreviations: Body mass index (BMI), Standard deviation score (SDS), SDS S5: 60–64 months after birth (SDSS5)
