From: Evaluation of clinical parameters influencing the development of bone metastasis in breast cancer
The decision tree derived by exhausted Multivariate Analysis (CART) illustrates that subcategories of BC, age at primary diagnosis, histological subtypes and grading are correlated with the appearance of bone-only metastases. Independent Variables: subcategories of BC, histological subtypes, age at primary diagnosis, tumor size, number of affected lymph nodes and grading. Dependent Variable: bone-only metastasis
