All other screening policies are shown in Online Supplement tables 3 (by screening frequency and start stop age) and 4 (PSA based risk stratification, PSAt dependent on age, screening men older than 75).
Reduction (-) or increase (+), in percentage, relative to base case (50-74, PSAt=3, yearly screening). Screening policies are ordered by overdiagnosis reduction.
PSAt stands for prostate-specific antigen threshold for biopsy referral, Overdx for Overdiagnosis, PCM for prostate cancer mortality.
