a The OR was calculated relative to never-exposed cases (n = 360 for Non-Proxy, n = 517 for ALL) and controls (n = 336 for Non-Proxy, n = 480 for All). Controlled for age at diagnosis or index year, family history of breast cancer, personal history of breast cancer (before current diagnosis or index year), age at first live-birth or still birth, occupational exposure to PCE, and vital status at interview (for All analysis only).
