Fig 1 Kaplan-Meier estimates of mortality, 1987 through 2005, stratified by four groups of panel reactive antibody (PRA) levels (0%, blue; 1 to 10, red, 11 to 25, green; and > 25, orange). Actuarial survival was calculated for the entire cohort and stratified by PRA level. *Comparison between each group and reference point PRA = 0% by log-rank test.

Fig 2 Kaplan-Meier estimates of mortality, 1987 through 2005, stratified by panel reactive antibody (PRA) level of 25% or less (blue line) or exceeding 25% (orange line). Actuarial survival compares patients with a PRA exceeding 25% vs those with less than 25%.

Fig 3 Kaplan-Meier estimates of mortality, 1987 through 2005 for panel reactive antibody (PRA) exceeding 25%, stratified by type of transplant (TX). Actuarial survival in highly sensitized patients is divided by procedure type. There was no significant difference between single- (SLT, green line) and bilateral-lung transplant (BLT, orange line) recipients.

Fig 4 (A) Kaplan-Meier estimates of actuarial survival, 1987 through 1997, stratified by panel reactive antibody (PRA) level of 25% or less (blue line) vs exceeding 25% (orange line). Patients with a PRA exceeding 25% have significantly decreased survival compared with patients with a PRA of less than 25%. (B) Kaplan-Meier estimates of actuarial survival in a more modern cohort, 1998 through 2005, stratified by PRA level of less than 25% (blue line) vs exceeding 25% (orange line). Patients with a PRA exceeding 25% did not have a statistically significant survival difference compared with patients with a PRA of less than 25%.
