With the β-coefficients of the Cox models, a prognostic index (PI) is calculated.
For practical application, the main product of a Cox model is a prognostic index (PI).
Variables were entered in the multivariate model as a prognostic factor when P values <.10.
In four out of five data sets, the proliferation signature is included in the model as a prognostic factor of outcome.
3 A diabetes risk score is an example of a prognostic model.
As illustrated by our study, the bootstrap model selection procedure may provide valuable additional information on model stability when deriving a prognostic model in multiple imputed data.
As an example, we define a prognostic model for outcome in childhood acute lymphocytic leukemia with the Cox model and use of a training set of 224 patients.
Based on the final model, we created a prognostic index to predict failed appointments.
However, if the goal were to develop a prognostic model, then model fit is of primary importance.
When transformed to a prognostic model, the expert-based models performed less well compared to a statistically derived model.
