"This review was prospectively registered with PROSPERO (CRD42020203131). Conclusion: There is limited evidence available to make a recommendation for/against continuing breast screening beyond the age of 75 years. Future studies should use more informative comparisons and should estimate overdiagnosis given potentially substantial harm in this age-group due to competing causes of death.: This review was prospectively registered with PROSPERO (CRD42020203131)."
