Figure 2 The Survival of Candidates Who Did and Did Not Undergo Heart Transplantation: Years 1990–2005

The actuarial survival of patients who did and did not undergo heart transplantation was calculated for 18,004 United Network of Organ Sharing (UNOS) status 1 candidates (A) and 30,978 UNOS status 2 candidates (B) listed between years 1990 and 2005 in the U.S. The results were stratified by 3 eras of listing: I (years 1990–1994), II (years 1995–1999), and III (years 2000–2005), respectively. The survival was calculated from the day of listing until death on the waiting list for patients who did not undergo transplantation or death after heart transplantation. The analyses were censored at time of removal from the waiting list due to worsening or improvement of condition or the day of last observation on June 1, 2006, and did not account for subsequent changes of UNOS status or temporary inactivation of status.
