From: Mammographic density as a predictor of breast cancer survival: the Multiethnic Cohort
Breast cancer survival stratified by radiation treatment in participants of a nested case-control study within the Multiethnic Cohort. Survival by mammographic density (low density = less than 35%; high density = at least 35%) was estimated by Cox regression with adjustment for age at diagnosis, ethnicity, obesity, stage of disease at diagnosis (in situ, localized, or advanced), and radiation treatment.
