CKAP2 and gastric cancer: Utilizing this nomogram, we were able to forecast the 1-year, 3-year, and 5-year overall survival rates for GC patients, taking into account factors such as age, clinical stage, and CKAP2 expression, as illustrated in Figure 2F. To evaluate the effectiveness and efficiency of this nomogram, we employed a time-varying ROC curve, revealing an area under the curve (AUC) for each of the 1-year, 3-year, and 5-year predictions that surpassed 0.6, as shown in Figure 2G. To further validate our model, we utilized calibration curves to assess its predictive accuracy.
