Sexually dimorphic patterns in maternal circulating microRNAs in pregnancies complicated by fetal growth restriction

Table 1 Demographic and obstetric outcome data for groups used for microRNA array profiling

Category	AGA n = 4	FGR (IBC < 3rd) n = 4
Age (years)	28 (27–35)	30.8 (27–35)
Ethnicity Caucasian:other Number (%)	2:2 (50%:50%)	2:2 (50%:50%)
Non-smoker Number (%)	4 (100%)	4 (100%)
BMI at booking kg/m²	24.45 (23–28)	24.05 (22.3–28.9)
Gestation at delivery (days)	280 (272–284)	278.5 (264–284)
Birthweight (gramme)	3207 (3040–3560)	2225* (1880–2880)
IBC	32.8 (21.5–46.8)	0.95* (0.1–3.0)
Male infant Number (%)	2 (50%)	2 (50%)
Gestation of blood draw (days)	252 (252–252)	252 (252–262)

Data are median and range unless stated otherwise. Participants were matched 1:1 on all demographic and obstetric factors, except for birthweight and individualised birthweight centile which were significantly different between groups (*p < 0.05 FGR vs AGA, Mann–Whitney test). Data analysed by Mann–Whitney (continuous data) or Fisher’s exact test (categorical data). AGA appropriate for gestational age, BMI body mass index, FGR fetal growth restriction, IBC individualised birthweight centile
