PCa detection during follow‐up was significantly associated with baseline PSA (multivariable Cox regression analysis, HR = 1.20; 95% CI, 1.17–1.23; p < 0.001), and baseline free‐to‐total PSA levels (multivariable Cox regression analysis, HR = 0.66; 95% CI, 0.54–0.81; p < 0.001) (Table 2). The gene discussed is KLK3; the disease is posterior cortical atrophy.
