Statistical analyses in Swedish randomised trials on mammography screening and in other randomised trials on cancer screening: a systematic review
Conclusions
The use of unconventional statistical methods in Swedish trials has led to overestimation of risk reduction in breast cancer death attributable to mammography screening. The constant risk reduction observed in screening groups was probably due to the trial design that optimised awareness and medical management of women allocated to screening groups.
