Structure of the analytical model (cohorts with screening). In a theoretical cohort, 100 000 subjects participated in the first screening. Resubmitting those who did not contract breast cancer to the next screening (excluding those who died of other diseases) by simulation allows the calculation of costs and effects for participation in screening at any age (for example, from 30 to 79 years). It was assumed that 100% of subjects underwent further examination and that the sensitivity of such examinations was 100%.
