Figure 3.
A comparison of pregnant women with fetal growth restriction (FGR; n = 41) and appropriate for gestational age (AGA) fetuses (n = 146) on A) sleep onset position, χ 2 (3) = 23.70, p < .001; and B) median (IQR) percentage of total sleep time in each position compared with separate Mann–Whitney U tests. The higher percentage of time spent overnight in the supine position in the FGR group was no longer significant after adjusting for gestational age at the time of the sleep study (p = .059).
