Table 3. Adjusted Rate of DDKT and MIRR for Pediatric Kidney Transplant Candidates under KAS.

MIRR was larger than the IRR of 3-year increase in waiting time. This means for pediatric candidates, moving to a DSA with a higher transplant rate is associated with a median increase in the transplant rate that is higher than 3-year difference in waiting time.

Note: DDKT: deceased donor kidney transplantation, aIRR: adjusted incidence rate ratio, MIRR: median incidence rate ratio. Waiting time included years from regularly administered dialysis or registration on the waiting list (regardless of creatinine or eGFR levels), whichever came earlier.
