The data below represents the visits for a single subject.
Row 1:
Data for the screening visit was gathered over the course of 6 days.
Row 2:
The visit called "DAY 1" started and ended as planned, on day 1.
Row 3:
The visit scheduled for day 8 occurred one day early, on day 7.
Row 4:
The visit called "WEEK 2" started and ended as planned, on day 15.
Row 5:
Shows an unscheduled visit. SVUPDES provides the information that this visit dealt with evaluation of an adverse event. Since this visit was not planned, VISITDY was not populated. The applicant chose not to populate VISIT. VISITNUM was populated, probably because the data collected at this encounter is in a Findings domain such as EG, LB, or VS, in which VISIT is treated as an important timing variable.
Row 6:
This subject had their last visit, a follow-up visit on study day 26, 8 days after the unscheduled visit, but well before the scheduled visit day of 71.
