This study was part of a larger cohort study on kidney transplantation, medical imaging, and atherosclerosis.11 (link),14 (link) All kidney transplants performed in adults (≥18 y) between December 2004 and September 2019 at the University Medical Center Groningen and Erasmus University Medical Center, where the CaScore and RI were available or could be determined, were consecutively included in this dual-center study. In line with the pretransplant screening protocol in both transplant centers, a CT scan was performed if either of the following were present: age >50 y, dialysis vintage >2 y, a history of peripheral artery disease or signs and symptoms of peripheral artery disease, diabetes, or prior surgery in the iliac fossa. Patients were not included for further analysis if Doppler ultrasound data were insufficiently reported or stored for reanalysis or if patients underwent a combined liver–kidney or kidney–pancreas transplantation.
