Kaplan-Meier analysis of event-free and overall survival according to KIR ligand mismatch and ligand status following unrelated hematopoietic stem cell transplantation (HSCT) in Koreans. (A) Event-free survival in recipients with KIR ligand match (n=149) vs. KIR ligand mismatch (n=5), (B) Event-free survival in recipient-donor combination of both with C1/C1 (n=103) vs. recipients with C1/C2 or C2/C2 and donors with C1/C2 or C2/C2 (n=51), (C) Event-free survival in recipient with Bw4/Bw4 (n=28) vs. Bw4/Bw6 or Bw6/Bw6 (n=126), (D) overall survival in recipients with KIR ligand match (n=149) vs. KIR ligand mismatch (n=5), (E) overall survival in recipient-donor combination of both with C1/C1 (n=103) vs. recipients with C1/C2 or C2/C2 and donors with C1/C2 or C2/C2 (n=51), and (F) overall survival in recipient with Bw4/Bw4 (n=28) vs. Bw4/Bw6 or Bw6/Bw6 (n=126).
