Fig. 5From: Risk factors, prognostic factors, and nomograms for bone metastasis in patients with newly diagnosed infiltrating duct carcinoma of the breast: a population-based studyThe calibration curves of the nomogram for the 1-, 3-, and 5-year OS prediction of the training cohort (a–c), internal validation cohort (d–f) and external validation cohort (g, h). The X-axis represents the nomogram-predicted OS probability; the Y-axis represents the actual OS probability. Plots along the 45-degree line indicate a perfect calibration model in which the predicted probabilities are identical to the actual outcomes. Vertical bars indicate 95% confidence intervalsBack to article page
