Population			Sample
n	%		n	%
Risk classification
1318	21.41	Localized — low risk	409	17.32
2498	40.58	Localized — intermediate risk	1052	44.54
1921	31.21	Localized — high risk	753	31.88
318	5.17	Locally advanced	116	4.91
100	1.63	Advanced	32	1.35
Type of treatment
4153	67.53	Radical prostatectomy (RPE) ^a	2121	89.80
45	0.70	Radical cystoprostatectomy (RCP) ^a	7	0.30
1018	15.94	Radiotherapy (RT)	130	5.50
149	2.33	Brachytherapy (BT)	37	1.57
782	13.36	Active surveillance (AS)/watchful waiting (WW)	63	2.67
9	0.14	Other local therapy	4	0.17

N.B.: The data are restricted to primary patients in 2017 in centers that recruited throughout the year; ^a including radiotherapy following radical (cysto)prostatectomy; there was a significant difference between the population and sample with regard to the distribution of risk classification (χ² = 21.80; P value = 0.00022) and to the type of definitive therapy (χ² = 457,52; P value < 2.2 * 10⁻¹⁶)
