Hello everyone, I would like your opinion. my data is score (before and after therapy) on radiographs made with x-ray instrument and score based on the judgment of the doctor. I thought I create a new variable which only highlights the improvements, understood as the positive difference between the scores before and after therapy (with x-ray instrument and the doctor's judgment). after which I created a contingency table and used the chi2 and v-cramer to highlight the correlation between the two methods.
there are more appropriate methods? Thanks for the attention
