Univariate analyses of pretransplantation risk factors for TA-TMA development. The cumulative incidence of TA-TMA was calculated and compared between (A) patients with poor PS (2-4) and those with good PS (0-1), (B) patients with an HCT-CI high score (≥3) and those with a low score of 0-2, and (C) patients who received HLA-mismatched HSCT and those who received HLA-matched HSCT.
