Table 1 Time-dependent AUC estimated via nearest-neighbor smoothing [15, 16] at one year post-waitlist registration and one year post-transplant for the modified and existing LAS models. 95% confidence intervals were computed via the bootstrap percentile method; p-values were estimated using the normal approximation and standard deviation obtained from the bootstrap replicates. 1000 bootstrap replicates were used
