RR incidence = rate ratio calculated as number of PCa detected / person years in the screening arm divided by the number of PCa detected / person years in the control arm.
RR mortality = rate ratio calculated as number of PCa deaths / person years in the screening arm divided by the number of PCa deaths / person years in the control arm.
