Methods	Clinical trial of women equally divided into 2 groups of 50 of delivery in water and normal delivery. It is not clear from this if there was any randomisation. The fact that all 50 women in the intervention (water) group all achieved a water birth suggests they were a cohort of women who consecutively achieved a water birth rather than a randomised group allocated to water immersion. Clarification has been sought from the main author
Participants	100 gravida 1 and to women; aged 16-28 years; gestational age of 38-42 weeks
Interventions	Immersion in water during the active phase of delivery (not clear if this is first or second stage)
Outcomes	Outcomes Amount of analgesia, pain score, oxytocin use, duration of labour fist and second stage, Apgar score, admission to neonatal unit, satisfaction with mode of delivery
Notes	We have sought clarification from the main author on whether or not randomisation was used; if so, what measure were taken to conceal the allocation; and for clarity on the nature of the intervention
