Hi, I have question which statistic test to use (if possible):
I want to analyse the use of medicines after an intervention. The dataset includes a control drug and an intervetnion group and the number of drugs after the intervention are statified into 4 different strata (dummy data below). Is it possible to calculate a p-value for each stratum ie. a p-value between control/intervention for "No drugs" and a p-value for control/intervention for "1-2 drugs" and so on.for
Thank in advance for help!

| Control | Intervention |
No drugs | 125 | 100 | p=? |
1-2 drugs | 50 | 60 | p=? |
3-5 drugs | 15 | 30 | p=? |
more than 5 drugs | 10 | 10 | p=? |
Total | 200 | 200 |
