KLK3 and metastatic prostate carcinoma: The results showed that SII (OR: 1.000, 95% CI: 1.000–1.001, p=0.044), neutrophils (OR: 1.410, 95% CI: 1.065–1.867, p=0.016), lymphocytes (OR: 0.331, 95% CI: 0.162–0.675, p=0.002), hemoglobin (OR: 0.978, 95% CI: 0.961–0.995, p=0.011), PDW (OR: 0.764, 95% CI: 0.642–0.910, p=0.002), and PSA (OR: 1.008, 95% CI: 1.005–1.012, p<0.001) were independent risk factors for metastatic prostate cancer.
