Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
End of trial will be approximately one month after the last subject has given birth. Thus, end of trial is not the last visit. This is in order to allow registration of birth outcome and possible hospitalisation of the newborn within the first month after delivery. |
