I have 200 patients who have prescriptions from a pool of 20 drugs, and 100 normal control volunteers who do not take any of the drugs in the pool of 20. Each patient has 0 to 6 prescriptions from the pool of 20 in random combinations. Some of these patients have elevated plasma levels of cholesterol, and I would like to know which of the drugs in the pool elevates the cholesterol levels.
To sum it up:
n=200 patients + 100 controls, each on a combination of up to 6 drugs from a pool of 20; some of the drugs appear only in combination with others
dependent variable: n=1 (cholesterol)
Question: Which drug(s) are responsible for the elevation in cholesterol. I already know that more than one of these drugs are responsible for the elevation, and I also know that some drugs have no effect. I would like to use SAS studio for the analysis.
Thank you
