Page History
At least 1 product variable is required in a BDS dataset. This requirement is satisfied by any of the subject-level product variables (e.g., TRTxxP) or record- level product variables (e.g., TRTP). All product variables defined in Table 3.3.2.1 are record level, meaning that the values contained in the variable may vary by record within a subject. Subject-level product variables are described in ADSL Product Variables #2for ADSL Datasets.
