Many thanks for the prompt response. However, I am afraid that it is not completely clear for me. I apologize, I am not a statistician. Sorry, may be what I will say make totally non sense, but what I understood is the following: Let's suppose that I need to predict cancer-specific survival using the variables X and Y. What I need to do is to develop a model that include these variables and predict cancer-specific survival using the competing-risks regression. Then, I shall calculate the "predictions" of this model at a certain time point, then I shall use these prediction as an "endpoint", and predict it using a linear regression model that include the same variables, i.e X and Y. Finally, I use the coefficients of this final model to develop a nomogram. Is that correct?
Many thanks again Should I calculate the "prediction" of the competing-risks regression model, and then use this "prediction" as an "endpoint" and predict it using a linear regression by including the same variables as predictors?
