Figure 4. The results of the multivariate Cox regression, nomogram (E) and model diagnosis process (B, C, D, F) based on the key members in the ceRNA network. Seven potential prognosis-related ceRNAs were integrated into a new multivariable model. The results of the Lasso regression suggested that all seven genes were essential for modeling (A, B). The nomogram was constructed based on the model (D). The ROC and the calibration curves indicated acceptable accuracy (Area Under Curve (AUC) of 3-year survival: 0.731; AUC of 5-year survival: 0.724) and discrimination of the nomogram (C, E).
