Kaplan-Meier estimated probabilities of OS at 5 years. (A) The estimated OS for the whole cohort was 78% (95% CI, 74% to 83%) at 1 year and 71% (66% to 76%) at 5 years post-HSCT. OS at both 1 and 5 years post-HSCT were influenced by (B) IEI subgroup, (C) the presence of bronchiectasis at HSCT, (D) splenectomy prior to HSCT, (E) hepatic comorbidity at HSCT, (F) the number of IEI-associated risk factors at HSCT (bronchiectasis, colitis, malignancy, GLILD, hepatic comorbidity, and splenectomy), (G) HCT-CI score, and (H) year of transplant. OS at both 1 and 5 years post-HSCT were not influenced by (I) age at HSCT. Estimated OS at 5 years (95% CI) are shown.
