The short version
- Participants can generally choose to leave a study at any time.
- Leaving should not affect the regular care you would otherwise receive.
- Ask how to stop safely and what happens to information already collected.
The principle
Consent forms state that taking part is voluntary and that you may decide not to join or may withdraw later. This is a core protection in research ethics.
Your regular care
The form typically says that leaving will not change your usual medical care or any benefits you would otherwise have. If it does not say, ask.
Stopping safely
In some studies, stopping something suddenly may not be wise. Ask the team how leaving works, so you know the safe way to do it and whom to contact.
What happens to your data
Ask whether information already collected stays in the study and whether you can request that no new information be collected. The answers differ by study.
