AdV, human adenovirus; BM, bone marrow; CMV, cytomegalovirus; CORD, umbilical cord blood; IQR, interquartile range; MA, myeloablative; PBSC, peripheral blood stem cell; TBI, total body irradiation.
Fisher’s exact or χ2 test was used for comparisons for categorical variables, and Wilcoxon rank sum test was used for continuous variables, as appropriate.
FLU (n = 8), RSV (n = 10), ADV (n = 1), and HMPV (n = 11).
