Figure 4. Odds ratios for the association between chemotherapy receipt and age or race.

Age [top, <50 years vs 50+ years (referent)] and race [bottom, Black women vs non-Black women (referent)] were assessed in relation to chemotherapy receipt. Stronger associations are observed between age and chemotherapy receipt, while most associations between race and chemotherapy are null or attenuate with adjustment for clinical factors. (Low-risk: tumor size ≤2cm, N0; high-risk: tumor size >2cm and/or N1+)
