Good day,

I would like to know what statisitcal tool I should use to compare four groups (one of which is a control) to each other, where results obtained are the number of persons diagnosed with a particular disease and the number of persons not diagnosed with the diesease for each group.

The groups are as follows:
Group 1: High repetition and high force
Group 2: High repetition and low force
Group 3: Low repetition and high force
Group 4 (control): Low repetition and low force

I am trying to find out whether force and repetition are dependent or independent factors in the development of a disease.
