Allocation to intervention
Randomised controlled trial
Query!
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Informed consent was sought from potential participants on the day of ovulatory dose of HCG. The randomization was performed by computer-generated program. Sealed opaque envelopes were used for allocation. When the use of HCG administration as the standard luteal phase support had been confirmed after oocyte retrieval, the participants were randomly allocated into either the study group or the control group on one-to-one basis.
Query!
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomization was performed by computer-generated program on one-to-one basis.
