Data represent no. (%) of patients, unless otherwise indicated. Mann-Whitney test was used for comparison of continuous variables, and either the χ2 test or Fisher’s exact test for comparison of categorical variables. Abbreviations: CRP, C-reactive protein; ICU, intensive care unit; NS, not significant (P > .05).
Comparison for Charlson index scores 0 versus ≥1.
Comparison for Charlson index scores 0 versus 1.
Comparison for Charlson index scores 0 versus ≥2.
Patients known to have traveled abroad within 2 weeks before onset of symptoms.
Comparison for Charlson index scores <2 versus ≥2.
Patients known to have had diarrhea, based on hospital treatment records.
Patients known to have had fever (>37.9°C), based on hospital treatment records.
Antimicrobial treatment with aminoglycosides, carbapenems, fluoroquinolones, macrolides, and tetracyclines was considered appropriate based on the susceptibility results (minimum inhibitory concentrations) of the bacterial isolates.
