Body Weight (BW)

Example

This example shows body weights collected at weekly intervals, including some records showing when the collection was not done. In addition, some records were marked as excluded from all calculations due to being out of the normal range for the test.

Row 1:	The "Y" in BWBLFL is an example of the use of baseline flag.
Rows 1-11:	Show records for body weight for subject ABC-001-001 at weekly intervals.
Row 4:	Shows that the subject was fasted in error prior to the body weight being taken. The value was excluded from calculations.
Row 7:	Shows a record that was excluded due to faulty equipment; the exclusion flag is "Y" and a reason for exclusion is included.
Row 9:	Shows proper use of the BWSTAT variable to indicate "NOT DONE", where a reason was collected when a test was not done.
Row 12:	Shows TERMBW collected along with an indication that the animal was fasted prior to collection.
Row 13:	Shows that subject ABC-001-010's body weight was taken on day 15, but this was not scheduled (reflected by the use of BWUSCHFL).
