  • a For calculation of sensitivities, only the serum sample closest to day 0 of each case was considered.

  • b Serologic diagnosis of IA is defined by at least one seropositive sample in the indicated period.

  • c Sera of high-risk patients were sampled ≤7 days following hematopoietic stem cell transplantation.
