Methods
This was a single centre, randomised, parallel, two-arm equivalence
study with an equivalence margin of 5%. The equivalence design was
chosen due to uncertainty about optimal dosing strategies in clinical
management of anaemia in pregnancy. The margin was determined via
clinical consensus of the organisation’s anaesthetic team. The trial was
approved by the Northern Adelaide Local Health Network ethics committee
(HREC/14/TQEH/LMH/122). All patients provided written informed consent.
