Flow diagram of infants included in the postnatal study of term infants from the UmbiflowTM International Study.
RI = resistance index (of the umbilical artery), AGA = appropriate-for-gestational age, SGA = small-for-gestational age, BW = birth weight.

Pregnancy and birth characteristics of the study participants, grouped by resistance index of the umbilical artery and by birth weight-for-gestational age categories.

Fat-free mass in infants in the first 6 months of life.
(A) Grouped according to normal and abnormal resistance indices (RI) of the umbilical artery Doppler, (B) grouped according to weight at birth in terms of appropriate-for-gestational age (AGA) and small -for-gestational age (SGA), and (C) grouped according to the umbilical artery RI and AGA/SGA classifications. Abbreviations: N-RI = normal resistance index (of umbilical artery Doppler); AbN-RI = abnormal resistance index; AGA = appropriate-for-gestational age weight at birth; SGA = small-for-gestational age weight at birth. Numbers in brackets are the numbers in the group at the 6/10/14/26 weeks’ time points, respectively. Error bars represent the 95% confidence intervals of the mean.

*Denotes significant difference between groups. Abbreviations: FFM = fat-free mass; AGA = appropriate-for-gestational age weight at birth; SGA = small-for-gestational age weight at birth; Normal RI = normal resistance index (of the umbilical artery Doppler); Abnormal RI = abnormal resistance index.
