In some nutritional studies, a supply of study product may be provided to the infant's caregiver, to be used between 2 scheduled visits. The data collected on this can be represented in the DA domain.
Example
In this study, the sponsor dispensed a number of cans to the subject to use between the study visits. In this study, it was important to note the number of opened and unopened cans returned (i.e., the volume remaining in the unopened cans was not required to be collected); the variable DACAT was used to represent "Opened" and "Unopened" cans returned.
