KLK3 and neoplasm: The initial model included patient age, PSA, PSA density, clinical tumor stage, side-specific biopsy data (i.e., percentage of positive systematic biopsy cores, highest Gleason grade group, largest tumor extent), and side-specific MRI data (i.e., presence of a PI-RADS 4/5 lesion, lesion diameter, level of suspicion for EPE, length of capsular contact).
