Discontinue subject
A subject may be discontinued from the research study at any time if the subject is no longer available or eligible to continue participating in the study. You can discontinue a subject, for example, if the subject is not following study procedures or maybe deliberately providing false information, and so on.
If needed, instead of discontinuing the entire subject, you can also discontinue certain case report forms (CRF) associated with that subject or their individual pages. It depends on the situation in which you are.

Once saved, the subject is discontinued. You can no longer use it for data entry.
Now, the Discontinued value is displayed for the subject's current phase, and there is no next phase available. They disappear from the table (thus, you cannot change the phase manually and the subject can no longer move forward in the clinical trial).
