^aExcludes women who had laboratory report result entered prior to their genetic testing (n = 86) or women who had >365 days between genetic test and laboratory report issued (n = 28).

^bAt time of High Risk OBSP referral.

^cIf a woman met more than one risk criterion after genetic assessment, the following hierarchy was selected: carrier of a deleterious gene mutation, family history and ≥25% lifetime risk, first‐degree relative of a mutation carrier (but declined genetic testing); women who are a first‐degree relative of a mutation carrier (but declined genetic testing) were excluded (n = 27).

^dBased on International Breast Cancer Intervention Study (IBIS) and/or Breast and Ovarian Analysis of Disease Incidence of Carrier Estimation Algorithm (BOADICEA).
