Figure 3. Building and validation of the nomogram predicting the OS of GC patients in TCGA-STAD and GSE84437 datasets. (A, B) Nomogram based on four independent prognostic factors of GC. (C, D) Calibration map for internal validation of the nomogram. (E–J) Time-dependent ROC curves of the nomogram for comparing the 1, 2, and 3 year OS of GC patients. Data in Figures (E, G, I) are derived from TCGA data, whereas those in Figures (F, H, J) are from the GSE84437 array.
