  1. Age and gestational weeks are given as mean ± standard deviation (SD).
  2. Miscarriages and previous live births are given as mean number (range).
  3. RM recurrent miscarriage; AA artificial abortion; POC products of conception.
  4. *Samples include five RM and five AA used for the genome-wide analysis.
