Figure 1. Risk for Metastasis in Young Women From the Colorado Young Women's Breast Cancer Cohort.

Figure 1.

A, Unadjusted distant metastasis–free survival (MFS) (log rank test, P = .02) (eTable 1 in the Supplement). B, Distant MFS adjusted for stage, age, year of diagnosis, and tumor biological subtype. C, Unadjusted distant MFS in women with stage I or II cancer. D, Distant MFS in women with stage I or II cancer adjusted for age, year of diagnosis, and tumor biological subtype. PPBC <5 indicates postpartum breast cancer (PPBC) within 5 years of parturition; PPBC 5 to <10, PPBC within 5 to less than 10 years after parturition; and PPBC ≥10, PPBC after 10 or more years after parturition. Panels B and D show estimated values from adjusted Cox proportional hazards regression models; thus, including the number at risk is not appropriate.
