Statistical help? Comparing proportions
K

Can anybody help me finding the right statistical test to use? I would like to compare the difference in proportion of resolved disease variables between two treatment groups. The patients were followed over time, at three different time points (week 2, 4 and 18). There are three different disease variables. Those disease variables are scored based on acquired images. The scores were either resolved or not resolved. So I would like to compare the proportion of resolved scores between the groups, for each disease variable and follow-up moment.

Here is an example of my data

Disease variable Treatment group Week Resolved Total
A X 2 3 13
A Y 2 5 9
B X 2 2 11
B Y 2 4 9
C X 2 4 12
C Y 2 3 9
A X 4 6 9
A Y 4 7 8
B X 4 4 8
B Y 4 3 8
C X 4 5 10
C Y 4 3 5
A X 18 5 9
A Y 18 6 7
B X 18 5 6
B Y 18 5 7
C X 18 5 7
C Y 18 5 5
