Two-part model structure of maintenance of renal transplant: First-year and subsequent-year management. (A) Decision tree for the first year after transplantation. (B) Markov model for years subsequent to the first year after transplantation. Adult de novo transplant patients progress through one focused phase of treatment. In the first year after transplantation (phase 1: decision tree [A]), patient outcomes result in one of four outcomes. Surviving patients enter phase 2 (Markov [B]), on the basis of renal function measures, and progress through four health states for the remainder of their lifetimes. SC, serum creatinine level.
