CodeDisplayDefinition
Milestone Milestone statusOne of a set of milestone events that once they have occurred remain true thereafter. For example once a subject has reached the "Signed Informed Consent" milestone they achieve a status of "Consented" that will be true thereafter, even when they have left the study. For a subject a number of these states can be simulataneously true and should be recorded.
Enrollment Enrollment statusThis is a status that can only have a single value at a given point in time. The subject is either on-study or off-study.
