The period of administration for each survey – from invitation to termination of data collection – was approximately 10 days, during which one reminder email was sent to non-respondents.

Survival of all study subjects was checked by the study team at the age of 23 months, or following the termination of the study data collection in December 2004.
They obtain consent for data collection during pregnancy and collect delivery outcomes from all known pregnancies and all deaths of pregnant women up to and including 42 days post delivery/pregnancy termination, and 28-day neonatal outcomes.
Therefore, based on current literature, we defined a priori a set of parameters for data collection regarding DMC characteristics, interim analysis and early termination.
Follow-up data collection was done at an average of 1.4 years after termination of treatment.
The 11-14 week outcome was unknown in 337 (10.6%) because of loss to follow-up, pregnancy termination, or the 11-14 week scan was scheduled after data collection closed.
Data collection in Repast Simphony consists of three phases, namely initialization, recording, and termination.
For 118 (20.1%) patients, no or other reasons for termination were recorded (e.g. some physicians stopped data collection after 6 weeks without recording a reason, if a patient experienced a satisfactory Hb response).
