Thank you for your interest in the study. This registration process should take only a few minutes of your time.
It is important that all sections of this registration are completed if you are considering taking part. If, for whatever reason, you are unable to complete your registration within 24 hours of starting it we will unfortunately need to remove the details you have entered in order to maintain the confidentiality of your data. It will however be possible to re-register, should you wish to.
