This model was developed using logistic regression (LR) and seven independent predictive clinical variables after MRI: age (years), type of biopsy (initial vs. repeated), PCa family history (no vs. yes), serum PSA level (ng/mL), digital rectal examination (DRE: normal vs suspicious), MRI-based prostate volume (mL), and PI-RADS v2.0 score (1–5) [12]. This evidence concerns the gene KLK3 and posterior cortical atrophy.
