I just wonder if you could help.
Now I have a slightly complex study, which has three arms, the first two are similar, but has different procedures during the treatment, hence their CRFs will be slightly different, and the third arm will have total different treatment, which means it will have totally different CRFs. How could I do this in OpenClinica?
I was thinking using sites for different arms, as I could handle different CRFs for different sites, but I have not figured out how to hide the event from each site yet.
Do you have any suggestions?
