Conditional information

Context information: 
This model contains additional variables to the well-known Nottingham Prognostic Index (NPI) risk score.1 It was based on a continuous function for calculating the probability of disease-specific death, which previously exhibited greater prognostic accuracy compared with risk group–based models.2,3

How this model should be used.
In addition to being useful for patient counseling, the model also has the potential to assist physicians in deciding whether adjuvant therapy is warranted in a given situation.

Model performance:
This model predicted disease-specific death more accurately compared with the Nottingham Prognostic Index (NIP) upon internal validation (c-index: 0.70 vs 0.61, respectively). Model calibration was considered adequate (Figure 1). External validation of the model is needed to further evaluate model robustness and generalizability.
