Two-year OS and RFS in 7/8 HLA-MMUD HCT weighted samples. OS with abatacept + CNI/MTX compared with CNI/MTX (A), CNI/MTX + ATG (B), and PT-Cy∗ (C) and RFS with abatacept + CNI/MTX compared with CNI/MTX (D), CNI/MTX + ATG (E), and PT-Cy∗ (F). Propensity scores were obtained from a logistic regression model including sex, disease, age, HCT graft source, conditioning intensity, Karnofsky/Lansky performance score, and CNI type as covariates. Based on weighted Kaplan-Meier method. Symbols represent censored observation. Patients were censored at 2 years after transplant or at time of last follow-up, whichever occurred earlier. Tables under each curve show the number of weighted patients at risk at each time point. ∗For PT-Cy, propensity scores obtained from a logistic regression model including sex, disease, age, HCT graft source, conditioning intensity, and performance score as covariates.
