Can I withdraw from the study?

Yes, you can withdraw from the study at any time without giving reasons. You will have to inform the study team of your wish by email or letter (details in this leaflet). We will then send you a Withdrawal from Study Form which you have to sign and send back to the research team at Imperial College. 

You can stop being part of the study at any time, without giving a reason, but we will keep information about you that we already have. We need to manage your records in specific ways for the research to be reliable. This means that we won’t be able to let you see or change the data we hold about you.
