For MCW 1) Yes the same date shift applies for all dates for a given patient 2) Random shift for each individual patient.

Can we ask how you apply the date shift (we also date shift in CAPriCORN). Do you apply the same date shift consistently for all dates for a given patient? How do you apply the date shift across a institution? Is it consistently the same date shift for the whole population or is it a random date shift for each individual patient in the population?

Technically, shifting is not a problem if we would know how it was applied (including values used for shifting). To be sure we are covered by official protocols, I am sending this to Charon. She will check approvals for the study and get back to all of us.
