Validation of the accuracy of predicting overall survival (n=50)^*

^*Validation was done for 10 times. At each time, 50 patients were randomly selected as the validation cohort and the rest of the patients were used to fit the model and for estimation of the optimum threshold of high/low risk. Once the model was fitted, it was applied to the 50 patients to classify them into high or low risk of death at the 3-year time point. From 40 to 44 patients were correctly predicted to be at high or low risk in all the 10 rounds, which gave an average accuracy of prediction of 85.4%.
