The subjects were women who did (case subjects) or did not (control subjects) have a diagnosis of invasive breast cancer. aP values are univariate and were derived using Student's t-test and include both BRCA1 and BRCA2 mutation carriers. Other values are means (standard deviations). bExcludes subjects with missing data on current height. cCalculated for pairs in which case subjects were diagnosed at age >30 years. dCalculated for pairs in which case subjects were diagnosed at age >40 years. NA, not applicable.
