a The following categories were used: age at surgery in years (<60, 60–64, 65–69, 70+); % Gleason grade 4/5 (<15%, 15–34%, 35–69%, ≥70%); cancer volume in cc (<2.00, 2.00–3.25, 3.26–6.68, ≥6.69); and preoperative serum PSA level in ng/ml (<9.1, 9.1–14.8, 14.9–24.9, ≥25.0).
b The FF genotype was considered as a reference category.
