High expression of the circadian clock gene NPAS2 is associated with progression and poor prognosis of gastric cancer: A single-center study

Figure 4 Construction of prognostic nomogram in gastric cancer. A: NPAS2, tumor-node-metastasis (TNM) stage, metastasis, and nomogram predict the receiver operating characteristic (ROC) curves of 1-year, 2-year and 3-year overall survival (OS) in gastric cancer patients; B: Nomogram predict the ROC curve of 1-year, 2-year and 3-year OS in gastric cancer patients; C: Comparison of time-dependent ROC curves between nomogram and NPAS2; D: C-index for nomogram, NPAS2, TNM stage, metastasis. ROC: Receiver operating characteristic; OS: Overall survival; TNM: Tumor-node-metastasis; AUC: Area under the curve.
