Personalized Survival Predictions for Cardiac Transplantation via Trees of Predictors (ToPs)

This website allows the clinician/user to find personalized survival predictions for different time horizons for a patient with specific features.

To make these predictions, enter the features of the patient where prompted and click "Predict"
