In this example, a subject's weight was collected at various points in time to evaluate the presence of cachexia. An estimate of the weight of the subject approximately 3 months prior to the initial pancreatic cancer diagnosis date was collected for use at baseline.
The Vital Signs (VS) domain is used to represent the subject's weight. (For simplicity, only the weight for 1 subject is included.) When the date of the weight measurement was based on subject recall, VSDTC and VSDY were not populated. If the actual date of the weight measurement was available, VSDTC and VSDY should be populated. VSEVINTX was used to represent the timing of the baseline weight. VSEVINTX was used because the interval for evaluation cannot be represented in a standardized ISO character format (See Section 1.3, Known Issues, for additional information).
