Question ID: 740308
I am trying to get a feel for the number of patients (participants)
who participate in clinical research studies (i.e. such as, to test
the effectiveness of a new drug).  In other words, is it more like 50
or more like 5,000?

I realize the answers may be all going to be all the board, but if you can
prepare a summary (only name of study and number of patients, as
outlined below) and link to the source for as many as possible for
what I'm paying, that would be great.

Study 1 - 50 patients (give link)
Study 2 - 40 patients (give link)
Study 3 - 25 patients (give link)
Study 4 - 750 patients (give link)
Study 5 - 100 patients (give link)
Study 6 - 50 patients (give link)

I don't care what kind of clinical study it is, just the number of
patients who participated in them.  Need this as quickly as humanly

Thanks so much.

Hi Rainbow:

It appears you or another researcher currently has the question
locked, but I'll answer your question.

Yes, that is the format I'm looking for.  I was looking for somewhere
in the range of 20 to 25 studies.
