This report summarises findings from a retrospective review of medical records of patients undergoing in-vitro fertilisation (IVF) treatments that inform the redesign of the STOP-OHSS trial (IRAS Number: 298619; SPONSOR Reference: STH20532; REC Reference: 22/LO/0015; ISRCTN: 71978064). The design features of the STOP-OHSS trial, sample size estimates, and the statistical behaviour of the design in addressing the research questions under different assumptions are presented. The limitations of the design and implications of early stopping on trial duration are also discussed.


Favourable ethical opinion for the STOP-OHSS Trial was granted by the London-South East Research Ethics Committee.
