Implications of clearing data

Queries on a cleared item

In a regular CRF with no itemsets, the following status changes occur:

• An Automatic query is changed to Closed.
• For manual queries:
  • An Opened query is changed to Answered.
  • A Candidate query is purged.
  • Other queries are unchanged.

    In a CRF with itemsets, queries on an itemset are treated as if the itemset were one item, and the same status changes occur as they would for an item. 

Itemsets

If an itemset is deleted, the deleted data is cleared. The audit trail records two entries indicating that the data was deleted and then cleared. 

Calculated control

The value of the calculated control is cleared if the calculated control depends on the cleared item.

CDD (customer-defined database) mapping for a cleared item

The value mapped to the CDD is cleared along with the value of the cleared item. 

Subject number

After you enter a Subject Number, you cannot clear it.

Randomization number

After you calculate a Randomization Number, you cannot clear it.
