Values were expressed as n (percentage, %) or mean±SD. P values for each group were derived from either unpaired t-test or Mann-Whitney test as appropriate. χ2 test or Fisher’s exact test was used for assessing distribution of observations or phenomena between different groups.
ICU, intensive care unit; IPA, invasive pulmonary aspergillosis.
