Which stattest?

[bollibompa]

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
