Analysis of graft survival by Kaplan-Meier method in groups of patients with different immunological risks of antibody-mediated rejection. a: living donor. b: deceased donor. G1: low risk, not sensitized recipients, solid-phase immunoassay with single antigen beads (SPI-SAB) < 10%; G2: medium risk I, sensitized recipients, SPI-SAB ≥ 10 < 50%; G3: medium risk II sensitized (SPI-SAB ≥50%); G4: high-risk, sensitized recipients, SPI-SAB-DSA+. For patients who received DD, statically significant differences were found only in the comparison between G1 versus G2 (P = 0.005) and G2 versus G4 (P = 0.047)
