In this situation, the sponsor maintained an in-house dictionary of tobacco brands. This allowed this sponsor to study products across studies using the same tobacco product code for each brand of tobacco product.  These codes were used to create a TO domain. This domain provided details on the brand of tobacco product used by the subject.  Data for two brands of tobacco are shown. The additional information was represented as findings about events (FASU). For the general questions about tobacco usage, the applicant assigned FAOBJ to "TOBACCO".  Otherwise, the name of the tobacco product (SUTRT) associated with the data in the row was represented in FAOBJ. The UPC code was used by the applicant to identify the product. FADTC is the date of collection, in this situation the applicant used the visit date.
