Due to the low number of patients (Table 1), we excluded the E. faecium BSI and P. aeruginosa BSI infection groups from the regression analyses (Table 2).
Abbreviations: BSI, bloodstream infection; IQR, interquartile range; LOS, length of stay; R, drug-resistant; Res, respiratory tract infection; S, drug-sensitive; UTI, urinary tract infection.
