The 1:10 frequency-match distribution of the hierarchical categories is not exact due to patients excluded due death occurring within 24 hours of admission.
Abbreviations: BSI, bloodstream infection; IQR, interquartile range.
Candida BSI cases and frequency-matched controls were placed into the first risk factor category for which they had a qualifying diagnosis. They remained in that category without regards to subsequent risk factors. Finally, for the control candidates, if they did not match with a Candida BSI case patient, they could not be bumped to a risk factor category lower in the hierarchy.
