This example shows different cardiovascular endpoints collected for 1 subject, including examples of both collected and derived baseline measurements. These endpoints were measured at a single point in time at 8 hours post-dose (CVELTM = "PT8H"), per the study protocol. Since the time point is not an interval with a planned start and end, CVSTINT and CVENINT are null.
Rows 1-2, 4-5:
Show measurements performed at a specific time. Note that the same test was performed multiple times on the same day for a subject. In this example, CVDTC is part of the natural key of the dataset (CVDTC contains both date and time), distinguishing one record from the next.
Rows 3, 6:
Represent the mean of the 2 previous rows, which make them derived records (CVDRVFL="Y"), and at the same time serve as baseline values (CVBLFL="Y"). CVDTC now contains information about the date (not time).
Row 7:
Shows an example of a measured baseline value. It is not derived (CVDRVFL is null).
