CT computed tomography, FAS full analysis set, IFI invasive fungal infection, SD standard deviation

^aGastrointestinal mycoses were suspected or confirmed gastroenteritis (diarrhea and abdominal pain, or incidence confirmed by fecal culture, respectively)

^bRespiratory mycoses included suspected or clinically confirmed pneumonia due to Candida or Aspergillus spp.

^cData unavailable from nine patients; ^gfive patients; and ⁱseven patients for fever, chest CT, and other imaging examinations, respectively

^dBody temperature (mean [± SD]) of patients with fever was 38.6 °C (± 0.7); data were collected from 1400 patients (missing data, n = 3)

^ePatients may have received more than one type of imaging examination

^fThe longest diameter of the lesion was measurable for n = 6 (0.2% of 438 patients); ^hn = 42 (1.7% of 914 patients); and ^jn = 5 (0.2% of 92 patients) for chest radiography, chest CT, and other imaging examinations, respectively
