Recruitment details |
473 participants from 49 sites in 7 countries (Belgium, Canada, Denmark, Germany, the Netherlands, Poland, and Spain) were randomised in this trial. The first participant was screened on 25-May-2021 and the last participant completed the trial on 06-Jan-2023. | |||||||||||||||||||||||||||||||||
|
Pre-assignment
|
||||||||||||||||||||||||||||||||||
Screening details |
557 participants were screened in this trial. Of these, 84 participants (15.1%) were excluded prior to randomisation. The main reason for exclusion prior to randomisation was screening failure (12.4%). | |||||||||||||||||||||||||||||||||
