The informed consent is a process that takes place before you can join the study. During this process, you will be told what you can expect from the study. You will be told who will seek your personal medical information, and how it will be kept confidential. A consent form will also be given to you to read. You are encouraged to ask questions both about the study and parts of the consent form that are unclear to you. If you decide that you would like to be part of the study, you will be asked to sign the consent form. However, even after signing the consent form, you are allowed to change your mind and withdraw from the study at any time.
