Sites of Synchronous Distant Metastases, Prognosis, and Nomogram for Small Cell Lung Cancer Patients with Bone Metastasis: A Large Cohort Retrospective Study

Figure 5

DCA of the nomogram for the survival prediction of SCLC patients with BM. (a) 6-month survival benefit in the training cohort. (b) 12-month survival benefit in the training cohort. (c) 18-month survival benefit in the training cohort. (d) 6-month survival benefit in the validation cohort. (e) 12-month survival benefit in the validation cohort. (f) 18-month survival benefit in the validation cohort. The x-axis shows the threshold probability, and the y-axis shows the net benefit rate. The black horizontal line indicates that no patients died. The green oblique line indicates the cancer-specific death for all the patients. The red line represents the prognostic nomogram.
