Kaplan–Meier (K–M) analysis showed that patients with lower age (p < 0.001) (Figure 4A), TNM stage (p < 0.001) (Figure 4H), PCa grade (p < 0.001) (Figure 4D), PSA (p < 0.001) (Figure 4F), and Gleason score (p < 0.001) (Figure 4C) had prolonged OS. The gene discussed is KLK3; the disease is posterior cortical atrophy.
