HELLO
I've got a data set containing about 2500 patients, of which 300
have my interest (Group A).
I would like to extract a sample of 900 patients (Group B) out of
the data set that match Group A in age, sex and some other
parameters. A Classical Case-Control study with 3 controllers for
each case.
Is anybody have a clue how the syntax look like??
