From: Evaluation of clinical parameters influencing the development of bone metastasis in breast cancer
Logistic Regression Models (LRG) describes the relevance of different variables for the development of bone-only metastases: black line: risk model I, independent variables: Age at primary diagnosis, subcategories of breast cancer red line: risk model II, independent variables: Age at primary diagnosis, subcategories of breast cancer, tumour size, nodal status, grading, Nottingham prognostic index. The Predictiveness Curve is a plot of cumulative percentage of individuals to the predicted risks [42]
