Figure 6. Nomogram plotting and evaluation. (A) Clinical characteristics and immunoscores were used to develop a nomogram for prediction of the 2-, 3-, and 5-year survival rates of oesophageal cancer patients. (B) The calibration curve demonstrated agreement between the predictive and observed outcomes for 2-, 3-, and 5-year survival. The 45-degree dashed line indicates a perfect prediction of the ideal model, while the dotted lines indicate the actual performance of the nomogram. The closer the dotted line matches the dashed line, the better the prediction accuracy. (C) Decision curve analysis of the nomogram and tumour stage for the 5-year risk among patients with oesophageal cancer.
