Figure 3. Adjusted survival curves for breast cancer based on Cox proportional hazards model with baseline hazards stratified by breast density and screening mammogram result.

Models adjusted for age, race/ethnicity, menopausal status, history of breast biopsy, and family history of breast cancer. Solid black line represents true negative screening mammogram result group; Dotted black line represents false positive with additional imaging recommendation group; Dashed black line represents false positive with biopsy recommendation group. Each breast density group is represented in panels A-D where A: Almost entirely fat; B: Scattered fibroglandular densities; C: Heterogenously dense; D: Extremely dense.
