  1. Data are reported as n (%). Numbers from column one (n=137), column three (n=70) and column four (n=1238) form the total Count with Me study cohort (n=1445).
  2. *There were in total 207 DFM pregnancies; DFM events from 70 pregnancies were excluded due to low counting compliance.
  3. ** In total 1238 non-DFM pregnancies were part of the Count with Me study, but are not included in the current report.
  4. aObstetric risk factors: Previous pregnancy with fetal growth restriction, stillbirth > 21 weeks, fetal malformations, severe preeclampsia, preterm delivery, and/or > 3 spontaneous abortions. General maternal health risk factors: known type I or II diabetes, chronic renal, hypertensive or coronary disease, inflammatory and collagen disease, epilepsy, hypothyreosis or coagulopathy. Data were collected from medical records.
  5. bAsphyxia or protracted delivery with pathological cardiotocography finding.
  6. cIntervention decided upon within eight hours before delivery, including acute and emergency cases.
  7. dNo pathology identified at DFM-related consultation, uncomplicated pregnancy ending in spontaneous vaginal term delivery of a healthy infant with birth weight > 10th percentile (adjusted for gestational age and sex), Apgar score >75min, no neonatal complication or transfer to neonatal care unit and normal placental examination findings.
  8. eSmall for gestational age, infections, Apgar score <75min,, malformations or transfer to neonatal care unit for conditions relevant to growth restriction or fetal distress (respiratory syndrome or cerebral irritation).
  9. fBirth weight < 10th percentile, adjusted for gestational age and fetal sex.
  10. gBirth weight < 2.5th percentile, adjusted for gestational age and fetal sex.
