Death percentages among the two groups are 20% and 10%, respectively. Of those in the dialysis pool, 10% die, and of those who survive more than one year after a transplant, 5% die and 5% go back to dialysis. a The expected number of years a patient stays on dialysis. b The longevity of a patient who starts on dialysis. c The life expectancy of a patient who survives 1 year or longer after a transplant. d The expected number of years before an at-least-1-year transplant survivor goes back to dialysis or dies.
