Mean ± SD reported for continuous variables. Count (%) reported for categorical variables. Number of suspected and newly acquired infections was compared using the Fisher’s exact test, and the average number of infections per patient was compared using the Mann-Whitney U test
Abbreviations: BSI bloodstream infection, EN enteral nutrition, ICU intensive care unit, RTI respiratory tract infection, SD standard deviation, SPN supplemental parenteral nutrition, UTI urinary tract infection
aThe denominator is the total number of newly acquired infections
