Comparison of invasive aspergillosis after nonmyeloablative and myeloablative HCT. Cumulative incidence rates of invasive aspergillosis among 163 patients undergoing nonmyeloablative HCT compared to 1673 patients undergoing conventional myeloablative HCT (1993-1998).²  The 1-year cumulative incidence rates of invasive aspergillosis (IA) were 14% after nonmyeloablative conditioning (dotted line) and 10% after conventional myeloablative conditioning (solid line). The diagnostic tests, the methods used to identify cases of invasive aspergillosis, and definitions of infection were similar in the 2 studies.²  Ticks on probability lines indicate dates of censoring at last follow-up.
