| †
A p-value gives the probability that a difference between observed and
expected is due to random chance. A
p-value of <.05 is usually considered statistically significant. |
| * Person years are calculated as days
(converted to fractional years). The
number of days from July 1 or from the date of first wait listing until
removal from the wait list or the end of one year. |
| ** The expected transplant rate is adjusted for age,
blood type, medical urgency status, time on the waiting list, and |
| previous
transplantation. |
| *** The expected mortality rate is adjusted for age,
race, ethnicity, gender, primary diagnosis, blood type, |
| time on the
waiting list, and medical urgency status. |
| Based on data available as of 10/31/2002. Release at www.ustransplant.org on
