Finnish screening arm had greater risk for high-risk prostate cancer. Risk groups were defined as follows: low risk was defined as stage T1–T2 with a Gleason score ≤6, M0 and N0. A moderate-risk PC was stage T1–T2 with a Gleason score 7, or T3 with a Gleason score ≤7, both with M0 and N0. High-risk PCs were either stage T1–T3 with a Gleason score 8–10, or stage T4 or M1 or N1 (with any Gleason score)
