Establishment and Verification of Prognostic Nomograms for Patients with Gastrointestinal Stromal Tumors: A SEER-Based Study

Figure 5

The calibration curves for predictions of overall survival (a-c) and cancer-specific survival (d-f) in the validation cohort at 2, 3, and 5 years after diagnosis. The dashed line represents perfect correspondence between the nomogram-predicted probability (x-axis) and the actual probability calculated from a Kaplan-Meier analysis (y-axis). Abbreviations: OS, overall survival; CSS, cancer-specific survival.
