Common forms

Regular forms contain data for a specific visit. Even if the same form appears in another visit, the form starts over in the new visit and data do not carry forward from the previous visit in which the form occurs.

Common forms are CRFs that contain cumulative data; for example, a Concomitant Medication or Adverse Event form. When a common form appears in a subsequent visit, it contains the data from all visits in which the form occurs.

Note: Be careful not to include the Date of Visit field in a common form when creating trial definition data.
