Multivariate Cox proportional hazard analysis of the scoring system (n = 581).

Risk factors	Hazard ratio (95% CI)	value	Regression coefficient	Points
Gleason score
<7				0
=7	1.35 (1.115, 1.642)	0.0022	0.30	2
>7	2.43 (1.689, 3.498)	<0.0001	0.89	6
Pre-PSA score
<10				0
10–20	1.39 (1.110, 1.749)	0.0042	0.33	2
>20	3.92 (2.805, 5.469)	<0.0001	1.37	8
EPE and margin
None				0
At least one positive	1.50 (1.223, 1.833)	<0.0001	0.40	2

Assignment of points to risk factors was based on a linear transformation of the β regression coefficients. The coefficient of each variable was divided by 0.3, multiplied by a constant (1.88), and rounded to the nearest integer. Total point is 20.
