KLK3 and posterior cortical atrophy: Derived logistic regression equations estimated that an absolute PSA increase of 1 ln unit (corresponding to 2.72 μg/L) implied an age-adjusted odds ratio (OR) of 2.72 (CI: 2.17–3.49), 5.3 (CI: 3.95–7.51), and 7.00 (CI: 4.93–10.54) in harboring any grade, advanced, and poorly differentiated PCa, respectively.
