Acknowledgements

The main acknowledgment is to the millions of women in England who took part in the AgeX trial. The contribution from many individuals at each of the participating NHS Breast Screening Centres listed below is also gratefully acknowledged, and we are hugely indebted to Professor Dame Valerie Beral who was instrumental in planning and conducting the trial.

The additional screening for the trial was funded by the Department of Health and Social Care.  The study team at the University of Oxford includes staff funded by the Department of Health and Social Care, the Medical Research Council, and Cancer Research UK.
