Patients will be measured 1. during an operation and 2. after the operation.
Measurement 1: During the operation with machine1 to assess whether the transplanted tissue is at the right location (Outcome is binary (right location vs wrong location)).
Measurement 2: Measurements will be performed 1 months after the operation with machine2 to assess whether the transplanted tissue is still at the right location and did not migrate (Outcome is binary, right/wrong location).
Research question: How well does a positive/negative result during measurement 1 predict the outcome of having the tissue at the right/wrong location at measurement2?
Which test is appropriate to answer the research question? I use SPSS.
Thank you for your time, I am looking forward to your replies. -Leif
