Ref.: reference group

^*Based on antibiotic susceptibility phenotype (MIC susceptible to gentamicin, clindamycin, and TMP-SMX)

^**Other infection type (n=46) includes 21 urinary tract infections, 19 intra-abdominal infections, 6 arterial or venous cardiovascular system infections.

^***These items measured each as continuous variables where odds ratio reflects changes for a one point change in the score.
