KLF13 and posterior cortical atrophy: In the univariate cox regression, we found that the Gleason score (HR = 1.977, 95% CI: 1.537‐2.541, P < .001), pathology T stage (HR = 2.597, 95% CI: 1.641‐4.109, P < .001), N stage (HR = 2.005, 95% CI: 1.203‐3.341, P = .008), KLF5 (HR = 0.957, 95% CI: 0.921‐0.995, P = .027) and KLF13 (HR = 1.089, 95% CI: 1.016‐1.167, P = .016) are associated with the RFS of patients with PCa.
