Predicting Major Outcomes after MCSD Implant 1 Risk Factors for Death, Transplant, and Recovery James Kirklin, MD David Naftel, PhD
Predicting Major Outcomes after MCSD Implant 2 Two approaches: Simultaneous parametric modeling of the probabilities of the time related events based on a patient’s risk factors Simultaneous non-parametric estimation of the probabilities of the time related events based on sub-groups of patients
