Record the date(and time) the participant/subject is randomized to a treatment or control group. The date/time should be recorded to the level of granularity known (e.g., year, year and month, complete date plus hours and minutes, etc.) and in the format acceptable to the study database. This CDE should only be included on the CRF if the study is a randomized clinical trial. Otherwise, it can be removed.
