Study versioning

A study version is a named collection of visits and forms with particular characteristics including order, repetition, and so forth. These specific properties determine which visits and CRFs display in the navigation tools in the user interface for the study. The InForm application allows concurrent use of multiple study versions. A single site can be assigned to only one of the installed study versions at a time, but during the life cycle of a study a site can use multiple versions.

Note: The study version must be updated if study protocol modifications are made.

Clinical view mapping is based on the concept of mapping all controls on a single CRF to a single clinical view. If a CRF has multiple modifications, the clinical view that is generated is based on the latest version of the CRF and on all previous versions of the CRF.

Because the generated clinical views are based on all versions of a CRF, if a particular version does not contain some items which were added to the form later or removed earlier, the columns that represent those items and controls have NULL values.
