GESTATIONAL HYPERTENSION
The primary outcome, spontaneous vaginal delivery rate although higher in the EMEP arm, the result (RR 1.15 95% CI 0.88–1.51) was not significant. The observed effect of EMEP on this outcome was smaller than that from pilot data (RR 1.2 95% CI 0.9–1.9) we used from Teo et al. [EMEP demonstrated positive results over HB on self-reported night sleep hours, agreement to having slept better, satisfaction with the sleep aid. The latter two outcome findings were entirely consistent with Teo et al. [In contrast to Teo et al.’s [ At present the causal pathways of poor sleep leading to adverse pregnancy outcome are not fully understood. Neither is it known what the magnitude nor the period of improvement in sleep there has to be to drive gains on pregnancy, labor and delivery outcomes. Poor sleep in pregnancy is associated with gestational hypertension [
