ABOi = ABO incompatible; ABOc = ABO compatible. Cells show N (%).
a)
Matched 5 to 1 on age at transplantation (within five years), gender, race, zero HLA mismatch status, retransplantation, and year of transplant (within ten years) to ABOi recipients.
b)
Recipients do not sum to total because of missing data. P-values represent the comparison between ABOi patients and the entire ABOc cohort, using a chi-squared test.
