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.
