We matched 900 breast cancer deaths (diagnosed 2008\u20132022; died 2012\u20132023) to 3600 controls by age (\u00b13 months), postcode and citizenship. Individual screening histories were reconstructed by deterministic linkage across five administrative databases. Conditional logistic regression estimated odds ratios (ORs) for breast cancer death by invitation and participation. Opportunistic mammography was modelled, and self-selection bias was corrected using a factor of 1.28.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Invitation was associated with lower mortality (adjusted OR 0.71, 95% CI 0.58\u20130.85).
