Table 1 Characteristics of monochrionic twin with selective fetal growth restriction (FGR) with normal (group 1) and abnormal (group 2) selective FGR twin umbilical artery Doppler

From: Placental glucose transporter 1 and 3 gene expression in Monochorionic twin pregnancies with selective fetal growth restriction

  Group 1 (n = 9) Group 2 (n = 6) P value
Maternal age at delivery (year-old) 32.2 ± 3.6 33.2 ± 3.7 0.60
Gestational age at delivery (weeks) 33.0 ± 3.1 31.6 ± 4.5 0.52
Birth weight discordance (%) 37.4 ± 8.1 42.0 ± 11.2 0.34
Birth weight of AGA twin (g) 1876 ± 575 1564 ± 813 0.36
Birth weight of selective FGR twin (g) 1203 ± 474 970 ± 493 0.40
  1. BW discordance = [(body weight of the AGA twin − body weight of the selective FGR twin)/ (body weight of the AGA twin)] × 100%
  2. GA gestational age, BW birth weight, FGR fetal growth restriction, AGA appropriate for gestational age
