GG 1, primary Gleason grade; GG 2, secondary Gleason grade; %BC+, percentage of biopsy cores positive; MRSI, magnetic resonance spectroscopic imaging.
*
Denotes models for which Gleason grades were not included because all patients used to create the models had Gleason score 6 (3+3) disease.
†
Denotes models that were validated in the present study.
