Time to microbiological clearance (days)	3.6 ± 2.4	3.7 ± 2.8	0.675
Length of ICU stay (days)	16.8 ± 31.7	14.7 ± 22.0	0.706
30-day Recurrence of same BSI	15 (5.0)	7 (2.8)	0.183

*Abbreviations: MALDI-TOF matrix-assisted laser desorption/ionization time-of-flight, ICU intensive care unit, BSI bloodstream infection
†P-values were calculated using the chi-square or Fisher’s exact test for categorical variables and Student’s t-test for continuous variables
