Can I schedule a visit backwards from another visit, such as with a Screening visit (Day -30 to -1) and a Baseline visit (Day 0)?

No, you can schedule visits only going forward, but you can set up this visit schedule a different way.

Here's what to do: Schedule the Baseline visit based on the Screening visit. Baseline occurs 30 days after Screening, with the following visit window:

• For the Before visit window, one of the following:
  • If you want to allow Baseline to occur on the same day as Screening, 30 days before.
  • If a day must occur between Baseline and Screening, 29 days before.
• For the After visit window, 0 days

You schedule all other visits that are relative to Day 0 from Baseline.
