Recurrence-free survival stratified by density reduction group. (A) Recurrence-free survival according to mammographic density reduction (MDR). Patients were divided into four groups, MDR ≥ 10%, 5% ≤ MDR < 10%, 0 ≤ MDR < 5%, and MDR < 0% (increased MD). (B) Recurrence-free survival according to mammographic density reduction ratio (MDRR). Patients were divided into four groups, MDRR ≥ 25%, 10% ≤ MDRR < 25%, 0 ≤ MDRR < 10%, and MDRR < 0% (increased MDRR). Survival curves represent the results of Cox proportional hazard models adjusted for age, tumor size, lymph node, histologic grade, adjuvant chemotherapy, and Ki-67 status.
