Cumulative incidence of the main end-points and corresponding relative risks
| End-point | Cumulative incidence | Absolute risk reduction (95% CI) | RR (95% CI) | P-value | |||
|---|---|---|---|---|---|---|---|
| Radical-prostatectomy group | Watchful-waiting group | ||||||
| Total no. | %(95% CI) | Total no. | %(95% CI) | ||||
| Disease-specific mortality | |||||||
| At 5 years | 30 | 2.3 (1.2–4.6) | 50 | 4.3 (2.6–7.1) | 2.0 (−0.6 to 4.7) | ||
| At 10 years | 30 | 9.6 (6.5–14.2) | 50 | 14.9 (11.2–19.8) | 5.3 (−0.3 to 11.0) | 0.56 (0.36–0.88) | 0.01 |

| At 5 years | 50 | 8.1 (5.7–11.6) | 79 | 9.8 (7.1–13.5) | 1.7 (−2.5 to 6.0) | ||
| At 10 years | 50 | 15.2 (11.4–20.3) | 79 | 25.4 (20.4–31.5) | 10.2 (3.1–17.2) | 0.60 (0.42–0.86) | 0.004 |
Taken from the data of Bill-Axelson et al.2 The absolute risk reduction and relative risks are for radical prostatectomy as compared with watchful waiting. RR denotes relative risk and CI confidence interval.
