Predicted outcomes and health economic results from age 30 years by strategy
No screening | Screen 50 | Screen 70 | Screen 60 | Risk-stratified 4 yearly to age 70 years | Risk stratified 2 yearly to age 70 years | Adaptive screening at age 50–70 years, interval of 6 years if PSA level < 1.5 ng/mL, 4 years if >1.5 ng/mL | Repeat screen every 4 years at age 50–70 years | Repeat screen every 2 years at age 50–70 years | |
