Bone Metastasis Free Fraction Curves of Stage II Breast Cancer Patients. Bone metastasis free fractions are shown for stage II breast cancer patients with medium (left) and high risk histology (right). Grey stair-like line indicates stage IIA and black stair-like line indicates stage IIB. Oblique straight lines indicate 3% per person-year (solid) and 1% per person-year (dotted) lines.
