Note: CI is given for overall survival. Multivariate analysis controlled for age, race, menopause status, and subtype, respectively. Criteria for subtype assignments are provided in the Supplementary Materials and Methods. Race referent, EA (presumed from self-reporting); menopause referent, postmenopause; subtype referent, Lum A.
