Overdiagnosis in breast cancer mammography screening stratified by age

This record contains two files. 

The first file is a dataset including the complete, reproducible search strategies for all bibliographic databases searched during this project. The search strategies were designed to answer the following research questions: 

• What is the estimated proportion of overdiagnosis associated with mammography‑based breast cancer screening by different age groups of women, compared with either no screening or screening conducted in alternative age groups?
• To what extent do estimates of breast cancer overdiagnosis vary between randomised, non-randomised, and modelling studies? 

The second file includes the PRISMA-P checklist
