Statistical analyses
Descriptive statistics were used to summarize patient characteristics.
Host and disease-related factors, as well as IMI incidence, were
compared between patients treated from 2006-2015 and those treated from
2016-2020 using a Chi-square, Fisher’s exact, or Student t-test, as
appropriate. Host and disease related factors predictive of IMI for
patients with and without a diagnosis of proven/probable IMI over the
entire time period (2006-2020) were assessed by univariable and
multivariable linear regression. For all comparisons, p values were
considered significant at alpha < 0.05. All statistical
analyses were performed using Intercooled Stata, version 14 (Stata Corp,
College Station, TX).
