Study design
Purpose of the study
Diagnosis
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Women who are planning for a vaginal delivery are enrolled into the study at 35-37 weeks gestation. All subjects undergo the same intervention (LVS and ARS), and therefore there is no allocation of treatment or concealment procedures.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
No randomisation is required, as all subjects undergo the same intervention (LVS and ARS)
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?
