I think that they recruited from specific surgeries rather than asked for general applications so they had a more limited regional scope. There were originally 298 people who were supposed to do it I believe.I would have been interested to understand how many trialist applicants they had, and sort of wondered if they were short of volunteers. I know from discussion with researchers and recruiting researchers that finding volunteers is always a struggle.
I just don't seem to fit any criteria for any of the studies I have seen. I don't even qualify as a "well" participant.
Hey ho. There are far worse problems around if you're me.
