I have two independent groups: Treatment 1 patients and Treatment 2 patients
I want to see if the morbidity of surgery between two groups is different
In group 1
13 had postop complications
2 had complications detected preop
22 had no complications at all
In group 2
3 had postop complications
9 had complications preop
12 had no complications
Therefore the surgical morbidity in group 1 is 13/37 and 3/24 in group 2.
What test could I use to check the difference and would I need to reclassify the groups to 1. preooperative or no complications and 2. postoperative complications?
Also I just would like someone to verify that a chi-square test was correct in this instance
In this test I removed preoperative complications from the numbers
13 postop complications
22 no complications
3 postop complications
12 no complications
Was I correct is using a chi-square test here?
