Subject Disease Milestones is designed to record the timing, for each subject, of defined trial disease milestones (see Section 5.1.4.3, Trial Disease Milestones).
See the implementation guides referenced in Section 1.2, Implementation Advice for this Model, for further guidance regarding use of additional identifier and timing variables.
