Developing a donation after cardiac death risk index for adult and pediatric liver transplantation

Table 3 Internal validation of the donor after cardiac death risk index in predicting donor after cardiac death graft survival

DCD Graft Survival (mo)	DCD-RI class
	DCD-RI ≤ 1, low (n = 10/27%)	DCD-RI 2-4, standard (n = 8/21.6%)	DCD-RI ≥ 5, high (n = 19/51.4%)

The DCD-RI was calculated for an earlier DCD transplant cohort (2001 - 2004). The table summarizes actual and predicted graft survival as calculated with the DCD-RI. The DCD-RI predicted survival showed good correlation with actual graft survival, as actual graft survival fell within the confidence interval of DCD-RI predicted graft survival. DCD: Donor after cardiac death; DCD-RI: Donor after cardiac death risk index.
