Nomogram model construction and prediction. (A) The nomogram model which includes the protein-based risk signature, age, gender, tumor grade and TNM stage is developed. The total nomogram score for each patient can be easily calculated based on the risk score and the clinicopathological parameters, which is then used to predict the 1-year and 3-year survival probability. (B, C) The calibration plots demonstrate that the nomogram model exhibits good predictability for 1-year OS and 3-year OS.
