Nomograms Predict Overall Survival and Cancer-Specific Survival in Patients with Fibrosarcoma: A SEER-Based Study

Figure 1

Identification of optimal cuto values of age of diagnosis and tumor size via X-tile analysis. Optimal cuto values of age were identified as 58 and 73 years based on overall survival (a). Optimal cuto values of tumor size were identified as 61 mm and 110 mm based on overall survival (c). Histogram and Kaplan–Meier analysis were developed based on these cuto values (b) and (d).
