Question

Question Posted 11/21/19:
Dear experts,
After looking at the REGISTRY file, I see that many participants went through screening without any indication of issues, but have no follow-up data - this includes even absence of a baseline appointment. Am I missing information? Or how do I find out why a participant may have passed screening but then failed to have any further appointments? Thank you.
