Hi HTH!

I have 25 065 samples (patients), and in these samples I have about 2300 patients with heart failure.
I thought it must have been big enough sample set.

Should I check for each variable that in each stratum there are minimum 15 patients with heart failure?
I mean e.g:
- check that among patients having diabetes mellitus is minimum 15 patients with heart failure - and in the same way for other diseases?
- and check for each drug, that among patients were administered for this drug are also minimum 15 patients with heart failure - and in the same way for all drugs?


Thank you:
Agnes
