Risk factor | HR (95% CI) | P value (chi-square test) |
|---|---|---|
Preoperative PSA (>=20 ng/ml or not) | 0.6(0.3 to 1.4) | 0.246 |
Pathologic Gleason grade (>7 vs. ≤=7) | 1.1(0.6 to 2.1) | 0.795 |
Tumor stage (pT3/4 vs. pT2) | 1.4(0.6 to 3.0) | 0.435 |
Positive surgical margin | 0.9(0.5 to 1.9) | 0.853 |
Positive nodes removed (2 or more vs. 1) | 2.6(1.3 to 5.1) | 0.005 |
